| Just know that "synthetic blend" does not mean 50% synthetic oil in the mixture. It could be 50%, or it could be 5%. The oil companies refuse to say. | |||||

| Hey Scotty, I just have a quick question about oil types. My truck uses regular full synthetic oil. Could switching over to High Mileage Full synthetic cause a slight leak at gaskets? Thanks. | |||||
| Answer to: Synthetic Oil or Not | 27Relevance | 5 years ago | billybob | Submit Your Question HERE | |
| On older high meilage cars where synthetic oil has never been ised switching to synthetic can actually cause leaks. Also, I think a lot of the benefits of synthetic oil is just marketing from the oil companies. Really it is more about doing your oil changes on time than anything else. | |||||
| Answer to: could more frequent oil changes or synthetic oil have extended my engine life past 310K? | 30Relevance | 5 years ago | Chuck Tobias | Submit Your Question HERE | |
| As others have said there are many variables. Would synthetic oil have helped a bit? Possibly, but it's hard to say. As an example, I have a 1986 Saab 900S (non-turbo) I've owned about 20 years that is just ready to hit the 300K mile mark. Driving has been mixed local and highway. (It used to be my daily driver.) Engine has never been opened up and still runs practically like new, smooth, responsive, no bad noises and doesn't burn oil. When I take it out I can wind the engine out to over 5000 rpm and it sounds great, no issues at all. Admittedly I have not ... | |||||
| Hyundai Accents With Defective Engines That Burn Oil Internally | 30Relevance | 3 years ago | vampirelibby | Submit Your Question HERE | |
| From: Libby Hodges <personal info removed> <personal info removed> <personal info removed> Subject: 2018 Hyundai Accent Bought Brand New From Nalley Hyundai Dealership in Lithonia, Georgia that has a defective engine: that burns oil internally. First off Hyundai was sued in a class action lawsuit for car engines: that burn oil internally: so the owners have to put oil in the car every other day; because the oil burns in the engine internally with no leaking on the ground. In the lawsuit Hyundai was ordered to pay over $210 million dollars out to correct the defective engines. Hyundai agreed to the settlement & assured everyone that the Hyundai Accent model did not have this defective engine. Enter my car several weeks ago: I checked my oil & notice that it was empty. Nalley Hyundai recommended over $1500 in preventative maintenence. I got the preventative maintennece issues done & paid the $1500. Several weeks later I checked my oil again & it was empty. I was pissed off: so I took my car Firestone they reconnended $360 worth of emission related repairs. I paid the $360 & got the repairs done. Several weeks later the check engine light came on again. I went back to Nalley Hyundai were I was finally told by the service manager that "Some Hyundai cars have defective engines that burn oil internally: & there is no oil leaking on the ground. Hyundai did go to court & say Hyundai Accents have this problem: but unfortunately I have found out that some do. Your car unfortunately is one of the few Hyundai Accents that had a defective engine: that burns oil internally. Nalley Hyundai has to do an oil consumption test before we can order you a new engine. That involves you getting a fresh oil change & driving the car & bringing it back with no oil in the engine. Nalley Hyundai of Lithonia, GA will then make a note of the low oil in the engine. We fill the oil up at your expense. Then you have to drive the car a second time & bring it back when there is no oil in the engine. Nalley Hyundai of Lithonia, Ga will then call Hyundia Corporate & open up a case to order a new engine. If Hyundai Corporate approves your engine: it will them take up to a year to put the new engine in: because every Hyundai Repair shop in Georgia is backed up with a year worth of repairs to fix this oil consumption problem & put new engines in many cars. Your new engine will have a year warranty & there is no guaranty: that Hyundai has fixed the defect in the engines: so there is no guaranty that this problem will not re-occur in the future." After hearing this I was mad as hell. I called Hyundai Corporate myself: they opened up a case for me & called Nalley Hyundai of Lithonia, Ga & said all they needed was an authorization from the dealership to order my engine. Nalley Hyundai refused to order my engine & said they had to follow the guidelines & give my car a fresh oil change: & have me come back twice with no oil in my car. I already had an oil change: & I am not due to get another oil change. Since then I brought my car back twice with no oil in the engine. Nalley Hyundai said the check engine light was coming on because I needed a new gas cap for $41.00. So I bought the new gas cap & Nalley Hyundai of Lithonia, GA did fill my engine up with oil for free one time. I feel that the Attorney General of the USA should order all Hyundai Dealerships in the USA to cease & desist from selling all cars until they can figure our what is causing the oil consumption problem in all engines & permanently repair & fix the oil consumption problem for good. I have called several attorneys to try & find soneone to take my case: so I can sue Nalley Hyundai of Lithonia, GA for selling me a car with Defective engine: when they were aware of the oil consumption problem & also sue Hyundai corporate for continueing to manufacture & distribute cars with defective engines in them even after Hyundai Corporate was sued in a class action lawsuit & ordered to pay over $210 million dollars to correct the dwfective engines. I need help. Also Hyundai Corporate was also sued because not only do their cars have defective engines that burn oil internally: their cars are also easy to break into & steal. Hyundai Corporate has done nothing to repair either of these issues: they should be ordered by the USA governmenrt to immediately stop manufacturing & distributing cars until BOTH THESE ISSUES ARE PERMANENTLY FIXED. ANY HELP YOU CAN GIVE ME WOULD BE GREATLY APPRECIATED, THANKS, LIBBY HODGES | |||||
| Synthetic vs conventional on first oil change? | 27Relevance | 5 years ago | Re-Pete | Submit Your Question HERE | |
| Scotty, I just bought a new 2021 Ford Ranger and my owner's manual says to use 5W30 synthetic blend. I have just over 2000 miles on my truck and I am starting to think about my first oil change, and I've always heard you say follow the specs on what type of engine oil your car uses. I have used Castrol for years, but my question is I noticed they have a full synthetic oil that is specifically designed for GDI high pressure engines. I think you mentioned to look for a label that says something like gf6? I know it's not good to switch between synthetic and con ... | |||||

| In all likelihood, it’ll be fine to go from conventional to semi-synthetic, or even synthetic, as long as the oil spec meets the manufacturers requirements. I have gone back and forth between conventional and synthetic in my Prius, and that baby has 300K+ miles. It’s mainly synthetic now. | |||||

| I've used synthetic oils in classics for YEARS and they have been fine. As @Doc said, you can also use a synthetic blend. Some monograde oils, primarily SAE 30 and SAE 50, are still easily obtainable. But synthetic oil offers better protection, lasts longer, and works better. Mineral oil is basically oil derived straight from crude. synthetic oil is man-made with additives, etc. Neither of these will harm a classic motor. Bear in mind as well that many classic cars are running newer powerplants, especially muscle cars, as guys who want more power find it ... | |||||
| How do I change my oil? | 29Relevance | 10 months ago | sereniTy007 | Submit Your Question HERE | |
| I have a 2000 Toyota Echo ( 118,000 miles). My dad taught me how to change oil, but it's been quite a while since I've done it. I bought some low profile Black Widow ramps that will give me the extra few inches I'll need to remove the oil pan drain bolt/washer and the oil filter. If I outline the steps I'll take, will you please tell me if I'm doing it correctly. 1) Drive up ramps and chock back two wheels. 2) Let engine warm up at least 5 minutes. 3) Turn off engine, unscrew oil cap from top of engine to create a vacuum so old oil flows better. 4) Remove oil pan bolt/washer ( 14mm, turn counter clockwise to loosen). 5) Let old oil drain completely, then clean area where bolt was before replacing oil pan bolt and new washer. 6) Remove oil filter ( unscrew counter clockwise) and let it drain completely. 7) Clean area around oil filter & check to make sure the gasket on old oil filter came off with the old filter. 8) Replace oil filter using an Original Toyota oil filter ( the one I need has a pre-oiled gasket). Screw oil filter in till it seats, then turn an extra 1/4 to 1/2 turn. 9) Fill with new 5w30 oil ( I use Castrol high mileage semi-synthetic), replace oil cap. 10) Let engine run about 1 minute and check for leaks while it's running. 11) Turn off engine and wait at least 5 minutes before checking the dipstick to make sure oil is at full. The things I need to know is: 1) Should I pre-fill the new oil filter with new oil before I place the filter back on the car ( my dad never taught me to do this, but I've seen many people do it on Youtube)? 2) I don't own a torque wrench so how do I make sure that I don't under or over tighten the oil pan bolt ( would it be worth it to buy one for this purpose)? I changed oil on my 1999 Toyota Corolla years ago, and I never had any problems ( I had enough clearance to do this without ramps). I guess I'm just nervous about doing it again because it's been so long and I've never driven up on ramps before. That's why I chose to get low profile ramps. I don't know if it matters, but I'm a 63 yr. old DIY kind of lady. Any help or advice would be appreciated. Thanks! | |||||

| RE: Did AT-205 destroy my car? There's oil everywhere! | 29Relevance | 9 months ago | JoyMarieHarvick | Submit Your Question HERE | |
| @chucktobias THANK YOU VERY MUCH FOR TAKING THE TIME TO HELP! There are completely new leaks within a week of using the AT-205. My mechanic told me he believes the product did this by changing pressure in the system. I was actually in shock so I'll have to get him to write down a better explanation. I go to a reputable mechanic that only works on BMWs. The reason I like them is because they're super honest. Yes my car is old but I keep up with my oil changes. The oil leaks I had were very, very minor. If I was actually getting oil on the floor I would've gotten them fixed instead of trying the AT-205. The reason they were even found is because I'm one of those [unfortunate] people who has hyperosmia so I detect odors at much lower concentrations than the average person. I'm like a human Bloodhound. Anyway there was very little oil leaking but I could smell the leaks. Within days of putting the AT-205 in the oil the smell got much, much stronger and my car started smoking under the hood. My garage went from having no oil on the ground to a puddle about 12 feet²! It sucks they had to pour out all the LiquiMoly I just got 2 months ago but they talked about the AT-205 like it was radioactive or something. My mechanic was horrified by what I did and said it was like "giving cancer to a car". I was so depressed because I can't afford another car and he said we may not even know the full extent of the damage for awhile. THE SHOP OBSERVED: Found active oil coming from oil cooler lines. There is an active drip when the vehicle is on. Recommend replacing the oil cooler lines. Vehicle is going to need extensive oil cleanup as oil is all over front of vehicle which can be danger to the drive belt and the upper coolant hose. Vehicle still has oil leaks coming from oil cooler and valve cover and possibly the oil pan. Recommend starting with oil cooler along with the oil cooler lines and cleaning oil residue in order to properly narrow down further oil leaks. RECOMMENDATION Perform oil filter housing reseal with both oil cooler lines. Also perform oil service. In regard to the engine shutting off on its own for the 1st time ever within 24 hours of putting the AT-205 in, they wrote: TECHNICIAN NOTE Scan vehicle for fault codes and found fault or turbocharger boost pressure low fault is currently not present but what's that twice. Could be possibly from oil leak and oil additive. Would like to start by fixing oil leak and cleaning and performing an oil change clearing the fault codes and test driving the vehicle to see if fault returns. | |||||

| I would use full synthetic if you can. Really as long as its getting changed every 40000 miles along with the filter its probably fine with either. I like to use the Havoline 5w-30 pro ds full synthetic. Its really good oil for the money. Its what I have always used. | |||||

| Answer to: june 2, 2021 episode about oil | 29Relevance | 4 years ago | MountainManJoe | Submit Your Question HERE | |
| Can we agree in saying the oil system is a closed system(sealed)? It is not. Engine oil lives in the crankcase. The crankcase is not sealed. It's vented to relieve pressure from combustion blow-by. oil vapors are sucked into the intake, burned, and leave out the exhaust. Also, a tiny bit of oil makes it past the piston rings, and is burned in the combustion chamber. Many cars lose up a quart of oil between each oil change. Likewise a little of combustion material (soot, fuel, exhaust etc.) from the combustion chamber also reaches the oil. The engine is constantly moving, and the metal parts rubbing against each other, wearing down. These metal particles are also picked up by oil. Can we agree in saying clean oil never loses its viscosity?? Nothing is forever. But it will last a long time in a sealed container. Can we agree in saying the purpose of the oil Filter is to remove dirt from oil?? Of course. If by "dirt" you mean any kind of contamination, including metal that wears off the engine itself. Anything larger than approx 10 microns. (width of human hair is roughly 80 micron) when it starts getting dirty to change the filter and NEVER have to change the actual oil. This makes no sense. oil gets dirty (for the reasons explained above). It passes through the filter over and over and over, and it still comes out black. So what makes you think that changing the filter will suddenly make the oil clean. It doesn't matter how many times you change the filter, the oil will remain dirty. Anything smaller than the filter mesh size stays in the oil. The filter is only designed to pick up PARTICLES. It has no effect on compounds that are DISSOLVED in the oil. oil also undergoes chemical breakdown. It reacts with heat , and the various substances in the engine. It also undergoes shear forces that thin it out. Some molecular bonds are broken. New ones are created. By the time the oil is used up, it no longer has the properties it started out with. You can verify this for yourself. Cook a cup or so of fresh oil on a heat source. You will see many compounds vaporize and come out of the oil. After a few hours, it will turn dark. If you pour out the cooked oil and fresh oil side by side, you will see that it has lost its ability to flow. i have heard using 1qts. ATF to 4qts oil helps keep engine interior clean is this true?? That is something people were doing ages ago. If you use good oil, and change it regularly, you should never need to "clean" your engine interior. | |||||
