| Going from conventional to synthetic oil in recently purchased high mileage car... | 41Relevance | 5 years ago | alexssali97 | Submit Your Question HERE | |
| ... fall off. Because of this I was wondering whether I should switch to Pennzoil High mileage full synthetic considering it’s mileage. I really want the superior protection full synthetic oils offer considering I will be using my car for work. But I have seen scottys video on oils and he mentions that you shouldn’t switch from conventional to synthetic. There are tons of anecdotes from people experiencing leaks from switching but there are also tons of anecdotes from people who’ve had zero issues with switching to synthetic. I’m really confused because I just ... | |||||
| Seafoam Ultimate Synthetic Oil Stabilizer | 39Relevance | 4 years ago | joshjaks | Submit Your Question HERE | |
| I have a 2014 Hyundai Veloster Turbo for me and a 2013 Nissan Quest for the family. I like both cars a lot and want to keep them running a long time. I also live in Idaho so we have some longish winters. I've watched your videos about oil stabilizers, and the Lucas synthetic is supposed to be okay for Asian motors. However, I'm a little worried. Some drivers complained about the Veloster having an issue where the bearings in the cam shaft would freeze up, punch a rod through the engines (if I remember right). Lucas synthetic is still a bit thicker than syn ... | |||||
| Answer to: Synthetic oil in my 1977 camaro | 33Relevance | 5 years ago | Chuck Tobias | Submit Your Question HERE | |
| I use synthetic oil in my '65 Marlin and '67 Rebel V8 engines with no problems. (The former even has an old-style hemp rear main seal.) However, those engines were rebuilt prior to introducing synthetic oil so the seals were fresh and there are no problems. If your Camaro still has its original 44-year old seals they may start leaking because synthetic oil flows and seeps much better than conventional oil. So I'd hold off on synthetic oil until such time as the seals are renewed. | |||||
| Should I use synthetic blend oil on my 1997 Chevy S10 4.3L that leaks oil? | 32Relevance | 5 years ago | Mackey | Submit Your Question HERE | |
| I have been using conventional for the life of the vehicle that I bought new. Has had oil leaks for about the last five years. Was thinking of changing to Valvoline Max-life High mileage synthetic blend, or Pennzoil Gold synthetic blend (dexos approved). Would this exacerbate the oil leaks? Or would synthetic blend be good for the longevity for the 4.3L V6? Not thinking about using full synthetic since the flow rate would seek out any leaks and exploit. I am planning to have the leaks fixed in the near future. Would like input now about oil blends un ... | |||||

| Hey Scotty, I have a 2001 Toyota RAV4, 2.0 L 4 cyl engine with 225,988 miles on it. Bought it in 2018 with 188,000 miles on it, but I have been using 10W30 full synthetic high mileage oil instead of 5W30 synthetic oil. I don't think the engine has any or much wear, I have been doing oil changes every 5,000 miles or less. My only worry is here in Chicago, during the winter with the oil getting thicker with the cold temperatures and dry starting the engine causing more wear. Should I start using 5W30 synthetic oil or continue using 10W30 synthetic high milea ... | |||||

| Full synthetic oil for old/high mileage engine | 31Relevance | 5 years ago | CarLover007 | Submit Your Question HERE | |
| Hello Scotty, I drive 2007 Honda CR-V with 195,000 miles. My owner's manual recommends 5W-20 oil for the engine. It also says "You may use a synthetic motor oil if it meets the same requirements given for a conventional motor oil: it displays the API certification seal, and it is the proper weight". Now, my mechanic suggests higher viscosity oil like 5W-30 oil and discourages using synthetic oil for my engine. He thinks that higher viscosity oil uses the space created by wear and tear of the old engine. I personally feel that my engine runs smoother in full ... | |||||

| If it hasn't been running synthetic up to now, I would swap back. synthetic oils have a lot of additives that older seals and gaskets do not like, so you tend to start seeing oil leaks when running synthetic on an older, higher mileage motor. | |||||
| Answer to: General Synthetic and blend oil question | 38Relevance | 4 years ago | MrBob | Submit Your Question HERE | |
| The price of 100% synthetic is not much more than the blends. I would tend to use a blend in a really old car, 20 years plus since those cars were made for conventional oil. Your car is 14 years old and as such was probably designed with synthetic in mind. I tried a blend once in a car that had synthetic and the car started to smell like an old car that was burning oil. I went back to pure synthetic and the smell went away. I could not find any leaks but the smell was unmistakable. I think synthetic tends to not break down during long term storage where as c ... | |||||

| 1998 Lexus LS400 which engine oil should I use? | 37Relevance | 4 years ago | HunterLs400 | Submit Your Question HERE | |
| Hey Scotty!!! I have a 1998 Lexus Ls400 with 228k I and the previous owner have been running full synthetic oil. Since the car is so old there a very high chance the upper and lower oil pan gaskets haven’t been replaced. Full synthetic oil is more acidic than regular oil. Older cars’ gaskets weren’t made to be able to handle full synthetic oil since it wasn’t very prevalent back then. Therefore, I was wondering if since they are older gaskets and I’ve been running full synthetic… if the gaskets may have worn out because of that? I know they are because t ... | |||||
| Answer to: Is Synthetic 5W-30 Safe? | 35Relevance | 4 years ago | Justin Shepherd | Submit Your Question HERE | |
| If your engine was maintained by prior owners, then going full synthetic won't cause any problems. If it wasn't, and and it's worn, the detergency of full synthetic oil can cause sludge and gunk to be removed that was keeping the engine sealed and leak-free. This is somewhat hard to judge ahead of time. synthetic performs better in extreme conditions. It flows better in the cold and provides better lubricity in hot conditions. I wouldn't use it and prolong the oil change interval. The manufacturers claim you can, I use synthetic in my 1999 Ranger w/ 279k an ... | |||||
| Answer to: Full Synthetic or Synthetic Blend Oil | 35Relevance | 4 years ago | MountainManJoe | Submit Your Question HERE | |
| "synthetic oil" is meaningless marketing jingo. There is no agreed upon standard called "synthetic" that you can measure an oil up to and say, "yup. This is synthetic oil". It's only a word they put on the bottle. It's just like vitamins, supplements, "organic" food. It's not regulated and what's in the bottle might have nothing to do with what's on the label. What you CAN rely on is oil classification standards. American Petroleum Institute (API) SN, SN+ etc. International Lubricant Standardization and Approval Committee (ILSAC) GF-5, GF-6, GF-6B etc. ... | |||||

| Answer to: Standard oil or Synthetic? | 30Relevance | 4 years ago | Doc | Submit Your Question HERE | |
| synthetic oil is demonstrably better than conventional oil in some applications. Older vehicles would probably benefit from a synthetic blend as opposed to full synthetic for which they were never designed. Since I change my oil every 3000 miles max, I use the correct weight for the temperature and use synthetic blend. | |||||
