| Answer to: Is 91 octane needed ? | 18Relevance | 2 years ago | avalon04 | Submit Your Question HERE | |
| The publication ‘Car and Driver’ indicates in it’s listing of specs for the 2014 Scion that premium fuel is required. The website: http://www.fueleconomy.gov also indicates that premium fuel is required for this vehicle. (those are the only two sources that I checked.) Mixing 7.5 gallons of 93 octane gasoline with 5.5 gallons of 87 octane in your 13.2 gallon capacity fuel tank actually yields 90.46 octane, LOL. (accounting for the 0.2 gallons which would be remaining in the fuel tank if you are able to drive it to the gas pump) But I am not sure if that is h ... | |||||
| Answer to: Rattling noise when accelerating, especially when trailering or up hill. | 18Relevance | 3 years ago | AdamB3024 | Submit Your Question HERE | |
| Hey, @Hixster. Well GM ended up replacing the Trans temp sensor. Shifts a ton better now but they didn't do anything with the rattling from the engine. Told me they "tested my fuel" and had 10 percent alcohol and that "I should run premium gas." I asked them how they determined it wasn't premium and they said "because my alcohol content wasn't right." I replied that it's standard to have between 10-15 percent in all grades of fuel... anyways... they charged me 200 dollars to not do anything with the car other than tell me to run premium.... WHICH WAS ALREADY ... | |||||
| Answer to: 2023 ford f150 vs 2020 Toyota tundra | 17Relevance | 2 years ago | Justin Shepherd | Submit Your Question HERE | |
| You're picking the wrong vehicles if you "value gas mileage". Trucks are gas hoggy, any way you put it. Sure, the EcoBoost engine may be more gas efficient when you're not towing anything. As soon as you start towing anything with substance with an EcoBoost engine, gas mileage goes out the window because the turbocharger is operating. Turbochargers force more air into the engine's cylinders than is possible with a naturally aspirated engine. Increased air must be accompanied with more gas to maintain the same fuel/ air ratios. gas mileage is also EPA-estimated, not based on hard facts; I once got 23 MPG going 55 MPH on the highway in my old Ford Ranger 4x4 during the most recent fuel crisis; that's compared to EPA estimated highway mileage of 17 MPG. it has a 4:10:1 rear end, and the 2WD model uses either a 3.08:1 rear end, a 3.53:1 rear end, or a 3.73:1 rear end (the larger the gearing ratio, the more torque you have, but MPG suffers). You also picked the wrong transmission if you want that truck to last. It's a joint GM-Ford-designed automatic transmission. Those transmissions were so badly made, they issued a couple recalls for them, and they still aren't right; they were so bad, GM and Ford will never work together on any project ever again. I would be getting the Tundra if I were you. Any "fixes" Ford makes is just to keep it going until 60,001 miles, or 5 years; then, it's on you when the tranny breaks down. If they cared, they would have fixed those 2012-2020 Ford Fiestas that had PowerShift dual-clutch automatic transmissions. Ford knew they were defective when they were installing them, and they didn't care. | |||||
| Answer to: Should I use premium gas | 17Relevance | 2 years ago | MountainManJoe | Submit Your Question HERE | |
| Well of course they are. As usual, just follow the money. "Top Tier" is a license that gas retailers buy so they can display the feel-good sign over their gas pumps. Who do they buy the license from? Car manufacturers. In return, owners manuals will send you to their stations. It's just paid advertising. | |||||

| Use top tier gas to help clean fuel injectors: Non top tier gas may or may not have enough detergents in them to clean fuel injectors. But top tier gas will have such detergents. That is why there is the Top Tier standard. | |||||
| Answer to: Is Premium Gas Helping My Catalytic Converter | 17Relevance | 5 years ago | Justin Shepherd | Submit Your Question HERE | |
| What gas are you using when you use regular, and is it from the same station? Bad quality gas can cause the catalytic converters to throw codes when they shouldn't. Have you tried running regular from a Top Tier brand? Sometimes things are actually that easy. New cars aren't like old ones, even though bad gas still burns, the computer doesn't like some byproducts. Haha. I personally only run Shell in my vehicles. I've never had an issue with catalytic converters acting up. | |||||
| Answer to: 1993 Chevy 1500 305 5.0 v8 engine light comes on | 17Relevance | 4 years ago | Isaiahchevytruck | Submit Your Question HERE | |
| When I turn my keys, no fuel comes out only when I press my gas, and i would had to crank it by holding my key over and constantly push my gas pedal. When it does I can rev it up but I couldn’t go in drive and press the gas because it would sound like it’s shutting off till I let go and it picks back up and idles fine. But I had it sitting for a month so I put a new starter with a new battery and it fired right up with no problems. Then I left to get fuel with no problems and as soon as I got done getting gas i press my gas pedal to leave and it cuts off and does this on what I just told you.. The engine light comes on only when key is turned on not cranked tho. When it is cranked engine light goes off. Also injectors don’t get as much gas as it should. Only sprays a little when pressing gas pedal. I got a new fuel pump and new fuel relay. I can’t press my gas pedal no more in park to rev it because it sounds and feels like it shutting off. White smoke from exhaust just a little tho. Barely visible and strong gas fumes inside and outside truck. Now when I try spraying starter fluid it still won’t crank just turn over and sound like it’s trying to a little. It’s a rebuilt motor just been sitting for a little over winter. | |||||
| Answer to: Fuel treatment | 17Relevance | 4 years ago | MountainManJoe | Submit Your Question HERE | |
| what do I believe about those claims? None of it.I believe SOME independent testing and hard data.Scotty has stated many times that gas companies are really greasy about what they put in the gas.Fact: gasoline is federally regulated. You can gas up at any gas station your whole life and be fine.There is SOME evidence to suggest that gas from "top tier" distributors might have some long term benefits . I have seen ONE unconfirmed study by the AAA. This was already discussed before. I personally take gas anywhgere. I don't go out of my way for any particular gas station. All of the ones near me are the big names anyway (Shell, Chevron, Esso, etc.). That means I get a good variety of whatever they're using, at least once in a while. I have never had issues with fouled up fuel injectors. If I get gas that has a little bit less detergents in it once in a while, it's not the end of the world. | |||||
| Answer to: Gasoline Fumes | 17Relevance | 5 years ago | Dion | Submit Your Question HERE | |
| THATS another problem aside for what I mentioned. In cases like that the gas reversing out will soak part of the body near the gas entry and sometimes into the interior of the body panels - thus causing fumes. What I would do is the pull the nozzle out slightly and fill your car with gas on the slowest click position to prevent gas splash back. NOW that might in time eliminate the gas fumes but now you have to figure out that if we went to 5 gas stations and you fill up the same way on all five...would you have the same five results as to the gas being shot back? If so then there is a problem with the venting system in your gas tank. If in some gas stations it does and then some don't...means that some stations nozzles do not act the same in regards to your vehicle.....You will have to test this theory out if you want... | |||||
| Has anyone ever bougth bad gas? | 17Relevance | 2 years ago | mynameisdeleted | Submit Your Question HERE | |
| I was reading here: (most interesting) ( a most likely very infrequent human error) (another infrequent and promptly-resolved extreme situation) I've also heard of old and degraded underground gas-tanks at stations leaking rain-water into the gas-supply after clean fuel is delivered to stations. I bet shady contaminated gas and neglected underground gas-tanks at stations have probably happened in a number of states. How would one know they have bad gas? How frequent is bad-gas at a station? | |||||
| Water in Gas Tank | 17Relevance | 3 years ago | RisingForever2023 | Submit Your Question HERE | |
| 1996 Dodge Caravan, 130k Miles, 3,8 liter v6 My friend had put some gas in her car, that she believes had water in it. It was less than half a gallon she says. Could some water in less than half a gallon of gas cause the van not to start anymore. Like it gets so close, but doesnt want to fully start. Like its right on the edge sometimes in starting but it wont. I just replaced her fuel pump and still wont start. Does anyone know of a easy way to drain the gas from these vans. My friend does not know much about cars and needs an easy way to remove the gas. Like is there a stopper in the gas tank cap, to keep people from stealing the gas? Couldnt she just put a hose down in there and remove the gas. If so does anyone know the size and diameter of the required hose. Thanks I appreciate all of yals help. | |||||
| Premium fuel for 2020 Lexus GX460 | 17Relevance | 3 years ago | adarzins23 | Submit Your Question HERE | |
| Is premium fuel absolutely required for a 2020 Lexus GX460 with the 1UR-FE 4.6L V8 engine? I bought this used with 26,000 miles. This exact engine is in many Toyota Tundra trucks but Toyota only requires regular gas for these vehicles. The compression ratio for this engine is 10.2:1. If I put regular (87 octane) gas in the Lexus, could it produce knocking and potentially hurt the engine? | |||||

| If you want the maximum horsepower of your car, use premium gas, but you do not need for normal driving and your car computer will adjust for lower octane gas without any harm to engine. | |||||
