I accidently put super unleaded gas.on my VW beetle 2002


That is not a problem it is actually recommended that you use premium 93-94 Octane fuel, if you put turbo blue (115) in it that would be a problem but 93-94 octane is the VW recommended fuel type.

I just purchased a 2006 VW Passat 2.0T. When I opened the lid on the gas tank area, there is a sticker indicating that they prefer I use "unleaded premium, 91 octane". Can I use ethanol 89...


yes you can use 89 octane, but at first it may seem like the car is not running right. don't worry the car is okay it is that the 89 is thicker than the 91. just give it some time.

Does the 09 es350 need 93 octane gas or will it run on 87 octane


you should have a factory affixed sticker inside gas compartment cover listing premium fuel only or also listed in your owners manual. Otherwise if you notice that you're vehicle is making a pinging sound while accelerating or climbing a hill for instance then you may want to step up to 89 or 93 octane and try to avoid purchasing fuel with ethanol added it's **** and degrades your fuel quality/octane ratio

What is the highest octaine gas that is safe for my CBR. in my area you can buy pump gas with high ratings, and i dont want to damage my bike.


I've used Vp racing fuels 100 octane in my 88 CBR 600 f1 Hurricane.. only because i ran out of gas at the track when i was racing, but at $8 dollars a gallon, I'll bring my own next time..! and i didn't notice a thing, but i do notice a major difference when i use 87 as opposed to 91 which my bikes frame info says use only 91 or higher octane only! i could have also used 110 octane right next to it but it cost even more...look racing fuel at tracks are mainly for low compression race engine that will have turbocharged engines in them eg 9:1 ratio 110 octane 10:1 100 octane 11:1 95 octane 12:1 91 octane. higher octanes in a higher compression ratio will sometimes make it difficult to start so dont go real high!

2001 sebring recently started sputtering at low rpms. Started after a recent fuel fillup. Tried dry gas and STP gas treatment. No change. Could this be a clogged fuel filter?


It could be but sounds like some bad gas, try using some octane boost because the gas you got might not have enough octane in it to run your car. So try using Octane boost and no its not the same as a gas treatment. gas treatment just cleans your lines and intake. Octane boost puts more octane in your fuel which is needed to run the car properly so try that.

Im curious about octane in fuel and what it does. I have a Nissan 350Z that requires 91 octane. Now if I were to put 94 or higher, would it improve performance or fuel efficiency at all or is it just a...


Octane is an added ingredient that burns more efficently than gasoline..use the 91 octane rating that your owner's manual specifies. Lower octane will degrade performance, higher than 91 is wasting money because it has more octane and is more expensive, but does not improve performance.

I use unleaded plus ALL the time for my car is that good or not good. whats the difference between regular unleaded, unleaded plus and super unleaded? which is best to use?


THE BEST THING IS TO USE WHAT YOUR SERVICE MANUAL CALL FOR. REGULAR UNLEADED 87 OCTANE - UNLEADED PLUS 89 OCTANE - SUPER UNLEADED 91 OCTANE. UNLEADED PLUS ITS OKAY. TO USE EVERY NOW AND THEN I WOULD USE 87.YOU CAN RUN 87 - 89 OCTANE.BUT DONT RUN 91 OCTANE ITS FOR THE HIGH PERFORMANCE ENGINE.

1984 Chrysler LaBaron fuel recommendation


Premium. Gas is rated by octane lnumbers and those numbers have stayed the same over the years. Mid gas would not have a high enough octane rating for your engine.
