I accidentally put the wrong type gas in my 2000 S430. I used plus instead of premium. Is this going to damage anything? Should I empty the tank?

Thanks

 

As long as its unleaded I would not think so.Here in the U.K. we cannot always get premium and so have to use plus instead with no ill effects.

 

89 Octane? How much did you put in? If a little, then fill the rest of the tank up with premium and be extra light on the throttle until the tank completely burns.

Also, try octane booster.

 

I wouldn't worry about it, don't do it often though.

The ECU will (I hope I get this right) retard timing enough so that your engine doesn't pre-maturely detonate causing a catastrophic engine failure. However it can only do this within the parameters as specified by the electronics so once again, be careful when putting in lower grade fuel in your car.

But since you only did it once, I wouldn't worry about it.

 

Thanks. I will run this out and make sure I am present when filling up my tank from now on. I love this car!

 

for the last 5 yrs, no problem whatever.

 

It is recomended that whenever 92 octane is not available use lower octane with caution which means ; don't push the engine into the higher rpm range ,try not to climb steep hills or put heavy loads on the engine.

 

My engine light came on. I called to schedule service and tech suggested that I run on out gas and see if light stays on after that. I can't really be sure if its from the gas or if its from the oil burning problem they said I have. I be constantly checking the oil. However it keeps reading "Not Possible" When I look at the stick its like 3 lines down from the top arrow. Do you think the engine light is due to the gas? It was exxon. Should I drive it out or just high tail it to the service center?

 

make sure the gas cap is on tight, that can set a code.

 

Gas cap was not on tight. I opened it and screwed it back on. How do I reset code?

 

Well engine light cleared today. Not sure how this works. I am just glad I didn't go to the shop. That would have been a whole lot more.
