Nothing special, that's how OBD II came about. Everyone is on the same field.

 

It will read and reset the obd-2 codes.

 

So got an OBD reader and filled it up with 100 octane, proceeded to put about 40 miles of "spirited" driving and so far no codes. Thanks everyone for your input, hopefully this takes care of it.

 

Yea, AM’s are sensitive to the octane level... I drop two bottles of the red STP fuel cleaner injector you buy at the gas station and keeps a smooth idle... poor octane gas will always kick the light on in AM cars in the US...

"Urgent Service Required" = add two bottles of fuel injector cleaner... you dont need to add more gas... light goes out in 10 miles on less..

I think folks underestimate how large the surface of the piston head x v8,12 and a 7 speed stick which combined with low octane = rough idle = "Urgent Service Required"

 

So fuel injector cleaner and not octane booster? I'll give it a try.

 

Growing up I was told there was no longer a need for fuel injector cleaning, since as of some year, long ago, gas stations started putting cleaners into their gas to prevent any buildup. Is that inaccurate information?

Also, are you recommending to do this on every tank?

 

As long as there are injectors in an engine you can use injector cleaner. I dont trust the cleaner in the gas to do the job.... Octane boost is 99% the same ingredient as injector cleaner. I add two bottles of the STP about every 500-1,000 miles... tank full or not...

I promise increased performance and smooth idle...

 

Got it. Thanks for sharing your experience as we don't have the best gas here. Have you bothered to check what code gets thrown when your MIL light shows? I would assume if octane levels are the issue that it would be a misfire code as the result.

 

Hey thx, I was unaware octane boost and injector cleaner were basically the same. I'll definitely give it a shot. Interestingly my light came on when I hadn't had time to mix some race gas in and tank was 100% 91 octane
