| Answer to: Shell gas or bp ? | 18Relevance | 5 years ago | BruceREE | Submit Your Question HERE | |
| Depends on the engine. If you have an engine with with direct injection, I would personally like more detergents, like a shell gas. Also matters with premium vs regular gas. Though modern cars use computers to adjust the range/setting with the type of gas you use. If you have car that recommends vs need to use a specific gas, I would go recommend or higher in terms of octane because going lower can shorten life significantly in the long term. I believe you are misinformed though as milage is more or less average per gallon or liter no matter the gas company. | |||||

| ... the rest. VPower, Techron, etc… they are all fine too, if one wants to pay the premium. The point being for the OP is that octane isn’t the main factor. It’s the detergents in it, and top tier is one of those options. You’re free to suggest other options to the OP. | |||||

| Scotty, I have a 2018 Honda CRV with a 1.5 L turbo engine. I have noticed that they have fuel injector problems and head gasket problems if I use premium gas even though Honda says to use regular will that help with fuel injectors, and I drive in turbo mode to keep the RPMs down will that prolong the life of the engine thank you, sir, | |||||

This can seriously damage the engine, or outright destroy it, especially if you have an old school carburetor and the engine is purely mechanical. The head of the piston is the weak part. You could easily bend or outright destroy the piston head using the wrong octane fuel, but not the entire connecting rod/piston assembly. You said yourself that premium fuel is recommended. You didn't say it's required. If it's a more volatile fuel (such as regular gas from the gas station), you will ... | |||||

| ... up with Shell premium V power Nitro plus. Within a few minutes the check engine light went off and so far has stayed off for about 30 miles which it hasn't done for months. Not sure if it's the premium gas or the better additives( I had been running regular in it prior to that.) Any thoughts on this? I did see a comment online of someone having a similar experience. I've never been a big Shell fan in the past. I've either run discount gas or Chevron.

| Answer to: Ethanol Free? | 19Relevance | 8 months ago | Justin Shepherd | Submit Your Question HERE | |
| Of course. Straight gasoline has an increased energy density as opposed to E10 (regular pump gas is E10). That translates to better gas mileage, theoretically. Fill up with straight gas and calculate your cost per mile traveled. That will give you your answer. It's likely not enough to warrant the increase in the gas price. We don't use most of the oil we produce in this country (the oil we produce is termed light, sweet crude, our refineries specialize in sour, heavy oil, which is a lot more plentiful and you can't easily swap between the two) The ethanol content also helps to thin out carbon deposits, as it's a powerful solvent. Personally, I went the other way and started buying E85 (my '14 F-150 is Flex-Fuel capable, I think your F-150 is as well, it would say on the tailgate, or look at the VIN) because it's over $1 cheaper than E10 and I'm getting 14.5 MPG vs 17 MPG. I go to the gas station slightly more frequently, but I'm saving a lot of money in the process. I also have a 37 gallon tank because of the tow package, so I don't really "notice" much of a difference. I can go 517 miles to a tank of E85 vs 667 miles on E10. gas prices rocketed to $3.50 a gallon last week because of flooding in Indiana. I found a couple gas stations nearby that have been selling E85 for $2.22 and $2.19 through the duration of the flooding. gas prices have since come down to around $3 a gallon. | |||||

| Energy Secretary’s Not-So-Excellent EV Adventure It’s rather amusing when promoting electric vehicles goes spectacularly wrong. EMMY GRIFFIN MORE BY THIS AUTHOR Summer road trips are always an experience, as Energy Secretary Jennifer Granholm just found out. Granholm set off on a four-day excursion in an attempt to promote the ease, convenience, and necessity of electric vehicles (EVs). She had an entire entourage of EVs with her, including the Cadillac Lyriq, a Ford F-150, and a Chevy Bolt. What she didn’t quite account for was all the extra planning and thinking she had to do to make this trip feasible. Even with all the help she had at her fingertips, the trip wasn’t exactly a model vacation. NPR sent a correspondent on the trip with Granholm to detail the journey. While documenting the trip, Camila Domonoske couldn’t help giving away important details that immediately undermined the purpose of the road trip — to be an EV advertisement. What was alluded to but not explicitly mentioned is that, along with their entourage of electric vehicles, there was also an advanced team of gas-powered cars used to ensure rescue and assuage other logistical concerns they had with their EVs. But even with NPR’s guaranteed leftist slant, it was hard to gloss over what happened next. Granholm’s biggest hiccup happened just as she was traveling through Grovetown near Augusta, Georgia. Granholm and her team needed to stop for a fast charge, and her gas-powered advanced team encountered a major problem. The charging stations were almost full, so one of the team members used their non-electric vehicle to save the last free charging station for the energy secretary. Along came a family on a road trip who also had planned a stop at this station. They noticed the gas car in the only free electric charging station. It was a hot day, they had an infant in the car, and their car was quickly losing charge. The injustice of being edged out of a station because of a gas car was deeply frustrating. So frustrating, in fact, that the family called the cops. Unfortunately for the family, there was nothing the police could do, so they were forced to wait. Granholm’s team eventually did some juggling, including sending the other EVs in the entourage to other, slower charging stations so that the family could charge their EV. This ironic situation and very bad PR for the energy secretary was the icing on the cake of a frustrating road trip. The planning that goes into a road trip with an EV is ridiculous. In spite of apps that should help locate a charging station on the fly, there is a lot more thought needed when picking one. You need to make sure there is a charging station within the EV’s driving radius. Then you need to make sure it’s the speed-charging station you need: 20-30 mins (fast) or 3-5 hours (slow). Then you have to make sure the location is compatible with your needs. Fast charging is preferable near a restaurant, and slow charging is preferable near a hotel. This is going backwards vis-à-vis all the advances that we have made in road-tripping with gas vehicles — you plug in your destination and there are easy gas stops all along the way. Moreover, we don’t really have the infrastructure to support a high volume of EVs on the road. There aren’t enough charging stations or units at the stations. EV owners occasionally report encountering a charger that won’t work, causing more delays, frustrations, and anxieties. Then there’s the impracticality of having to make long stops for recharging. Even having to stop 30 minutes for a fast charge is slow when compared to stopping at a gas pump. Not only that, but charging an EV is still more expensive than pumping gas. According to Business Insider: “Charging any of these vehicles at home will run about $12.62 per 100 miles while fueling one at a gas station may run about $11.08. That difference, while not incredibly substantial, may add up — and when these drivers go to a public charging station, they’re likely to pay about $16.10 per 100 miles.” Perhaps the biggest hiccup of all for the “green” electric vehicles is that, ultimately, they aren’t cutting carbon emissions. Those charging stations are run by electricity, and electricity is primarily produced by carbon-emitting plants (mostly because ecofascists are against carbon-free nuclear power). The more electric needs there are, the more electric plants are going to be needed to provide enough electricity. The “green technology” of electric vehicles doesn’t match the hype of climate activist politicians like Secretary Granholm. It is not close to where it needs to be to present a positive, practical, and energy-efficient means of transportation. If having the cops called on Granholm didn’t illustrate that fact, the other inconveniences of the trip should have. Another point that should indicate to the “green energy”-pushing politicians that they’re doing it wrong is that they feel like they have to sell it to the American people. If the tech were practical and improved the lives of everyday Americans, they would buy it unsolicited. That’s how cars gained prevalence in the first place over horses and buggies. | |||||

| 2020 Acura RDX 2.0T- why premium gas, when same engine in Honda says Regular? | 18Relevance | 3 years ago | Jiminwisconsin | Submit Your Question HERE | |
| Scotty, Love your YouTube channel ! I have a 2020 Acura RDX, 2.0T with 50,000 miles. Reading the owners manual on page 355 under the heading “Fuel Recommendation “ it says “”Unleaded premium gasoline …91 octane or higher”. In the description it says that use of a lower octane could cause metallic knocking…and will result in decreased engine performance. Use of …octane less than 87 octane can lead to engine damage..” My question is why does autos mfg by Honda use regular gas? Is Acura just trying to “jack-up” their mpg records? I love this car!

| New Highlander died on bridge | 19Relevance | 4 years ago | ZRock | Submit Your Question HERE | |
| Good Day Scotty, I Leased a new 2021 Toyota Highlander from Sansone Toyota in Avenel, NJ on 05/06/2021. On my way to work on 05/17/2021 it just died on the Bridge with only 230 miles on it. I Almost got killed. Vehicle was towed back Sansone and I wasn't able to get to work that day. The next day I got a rental/loaner from them. The vehicle is a lemon and has issues. They are pinning the blame on me saying I added bad gas. The majority of the gas was still there's. Fuel was added at Mobil on 05/11/2021 almost week before it just died. The scammers are saying the vehicle needs a new engine and the warranty is voided. I am responsible for all the cost. It's weird because the night the vehicle broke down and was being towed to Sansone, they were already mentioning it sounds like bad gas before the vehicle even arrived there. On 05/27/2021 I was informed by Sansone that the vehicle had bad gas in it and I am fully responsible for the cost of all repairs. I disagreed with them but they didn't care. Toyota Corporate was totally useless saying why would Sansone Toyota lie and They stand by the Dealership. When I spoke to Carl the service Manager I informed him that most of the gas in the vehicle is from there original gas fill up. He didn't care and said it was my gas and I had filled up several times because the vehicle has over 900 miles. Vehicle only has 230 but he didn't care. On 05/27/2021 I called GEICO for help and the opened a claim. The Adjuster inspected the vehicle and took several pictures. Th Geico adjuster had issues with Sansones gas theory and bumped it up to their investigations unit. They never paid the claim believing it's a warranty issue. The Mobil gas station has had no reports of selling bad fuel. I had to pay a large sum of money for them draining the gas and changing the spark plugs. I had to have my broken down vehicle towed out of the dealership. They also charged me for the loaner vehicle. I had to hire a lawyer and I am paying every month for a vehicle I can't use. I am currently in Limbo and this is causing me unnecessary stress. I am writing you because I know you love Toyotas, but it's been a living hell for me. Thank You | |||||
| 2008 Lexus RX350 multiple questions | 19Relevance | 4 years ago | Kj2500 | Submit Your Question HERE | |
| hey scotty,, i bought a 2008 Lexus RX 350 with 211k miles on it engine and transmission smooth as butter,, only problem is after fixing the a/c the car started to do a slight idle drop and i thought it was the a/c compressor straining the engine,, now when i turned off the a/c to see if it will still do it, i was wrong, it continued to do the idle drop. Now I never replace the fuel injectors yet or the fuel pump I haven't replaced that as well,, & the car didnt came with any maintenance history papers. But what was done to the car though was a coil pack replacement, all sparkplugs and intake manifold seals the rubber seals,, and some sawdering done to the coil pack wires to rewire some pigtail sensors that connects to the spark plug tube sensor. But after doing all of that and adding freeant to the car is when the car started to do the idle drop thing it was doing. so my questions to you are if you know, does the car have a fuel filter built in somewhere on the gas tank outside? or inside the gas tank? or on the fuel pump? please see : I had to use lacquer thinner to make the car stop the idle drop thing but after I added the lacquer thinner I added 2 gallons of gas at a one gas station and it ran fine no problems at all. Then when I added some gas from a other gas station about 1.5 gallons (less gas) it started to do the idle drop thing. so I don't know if that means it has water in the gas at the gas station I took less gas from. | |||||
| Wrangler jku gas cap light | 19Relevance | 4 years ago | Bminus | Submit Your Question HERE | |
| I have 2011 Jeep Wrangler 4 door jk. 130k miles. The gas cap light keeps turning on along with the check engine light. I changed the gas cap twice. I changed the fuel gas cap cover because the rubber ring was ripped, Changed the evap emissions detection leak pump and the canister purge valve. Codes keep popping up for P0456 and P0455. I cleared the check engine light but the gas cap keeps reading open and the check engine light comes back on. The gas cap lid I was using for a few years was a locking cap and the locking mechanism seized up on me but good thing it was unlocked so I did not have to pry it off. I also have trouble keeping the gas pump pumping on automatic at the gas station. The gas cap problem started happening a week after I had my exhaust manifold worked on (not sure if it’s related).
