Its just i need to get my car on the road and i cant get to a dealers very easily but im going to get some service stuff tomorrow.

CMD Pointing Forward's!!!!!!!!! CMD said:. I am not going to change the oil myself or pay anyone to do it. However, the dealer also told me that synthetic oil is not included in the free maint. My first change is at , but I need to add some oil before this interval. Is it ok to mix regular and synthetic and when the oil change interval comes around will it be fine to put regular in the car? I have heard many stories about once you go synthetic you can't go back, is this true and if so why not?

Anyone else have the dealor tell them that their A4 came with synthetic? Is there anyway to tell if it is really sythetic? October The only cars that normally come with synthetic do so with the understanding that synthetic will be used for the entie life, true of Mercedes, Corvettes etc.

For a dealer to say the car came with it but will not replace it under the maintenance agreement is pure bull. I will bet that the fee they wish to charge for you to get synthetic will be more then you could get it done elsewhere??

I would go up the ladder on this one, pure dealer misrepresentation. Ross answered 13 years ago. Hi-test, 93 octane is all I used when I owned mine.

Used 89 once and i noticed a lag, idk if you will with 91, but the 93 for me worked great, and do not use fuel additives, they are a waste and actually corrode your gas tank.

The dealer not Audi dealer never told us to use Premium gas! I filled the tank with regular and now the car is running crappy I was advised to put an Octane booster in which I did. Still knocking Thank you for the reply I do not think it is "pinging" I don't hear any loud noises It was running wonderful until after I filled the tank with reg gas the next day it started running bad and trying to get passed 45mph is very shaky.

Also idling at a light the car vibrates terribly! I don't know anything about cars so I am concerned putting the regular gas may have damaged something Hopefully running the gas out and filling with 93 octane will help significantly. Is driving it until then hurting the engine? I did put one bottle of octane booster in the tank Thank you for your help! Cole answered 12 years ago. Adam answered 12 years ago. Don't run the tank out, drain it put the right stuff in.

I believe the 1. At that compression predetonation will happen regardless of retarding timing so damage will begin to occur, it's not like the c where it can sacrifice it's efficiency to prevent damage. SRT8 only runs Sorry was meant for the guy who said ' Hopefully running the gas out and filling with 93 octane will help significantly' Too many conflicting answers! I guess I will see about emptying the tank somehow Chase answered 12 years ago. Tim answered 12 years ago.

Good lord there is some serious misinformation in this thread. Motronic uses the engine's knock sensors to retard timing, but it can only do so up to a certain point -- about 15 degrees. Stay out of boost if you can, drive it at part-throttle and shift early.

Keep the load low and you'll have enough overhead that you won't blow anything up. To the user whose car is already running poorly -- you have a bad coilpack and one of the cylinders is misfiring.

That's why the check engine light is flashing. This is unfortunately incredibly common. Stop driving the car. Get a diagnostic tool and scan your car so you can figure out which one it is.

Go get a new coilpack from the dealer or an independent parts place and swap it in. You don't need any tools, it takes 2 minutes. Old one pops off, new one pops on. If you need more help, go over to forums. Worse-case scenario, have it towed to the dealer. Anthony answered 12 years ago. Why would you not put premium in it? I only use premium. Matthieu answered 11 years ago. Hi, I had the same exact problem with my Audi A4 1. I did fueled on Regular 87 , then Premium 91 , then regular 87 , etc.

Now I know it's a bad mistake! Stick with Even when the prices are sky high! I also ended up replacing all 4 spark plugs and 2 coils I will change the other 2 this week!

I also have a rubber hose that has a vacuum leakage Please check this link for further infos Many other guys have had the same problem! Kyle answered 11 years ago. I did use plus once 89 and noticed a difference. My friends say its all in my head and say i should use regular but i notice a big difference right away and use 93 ever since! ConspiracyRealist answered 10 years ago. Kevin, don't believe all the Dale Jr.

Using regular turbo engine or not does not blow up your engine, nor does it do any damage to your turbo. It does lower the performance output of your car, but let's get real. Will you be able to smoke the asian kid with the suped up ricer if you use regular? Probably not. Will you be able to quickly accelerate for lane changes and passes? It's all about what you want to do with your car. Not saying you did and no offense Don't feed into the hype about Premium vs. Regular gas, especially from people who only know what they read on the internet.

Does anyone here on the forums have a degree in mechanical engineering or chemistry? Most likely not.
