weird - i don't know how reg gas can kill an s2000.. maybe a contaminated fuel filters / injectors..

 

till all the regular is gone , tell him to drive it normal no heavy throttle movements and no Vtec ...... Or he will be visiting me

 

i agree with mike - gas no matter what grade wont kill the car - it might make it ping a little but not ruin it

 

correct, but heed what scott says. This if fuel is what it is a severe case of bad fuel. Never heard of it that bad b4 especially from a modern gas station.

 

The car pulls tons of timing combined with high temps and poor fuel can most definitely make the car run like crap .

 

i thought i read somewhere if you gas up with 89 you do not want to engage into vtec maybe he drove it hard?

 

so scott to clarify right now he should reset the ecu give it a little bit and try to run it if it runs than lay off keep the revs low till the fuel is gone and def get the cel code pulled correct?

 

never read that in the manual - i think it says you can run reg gas if need be

heck - i rented an s2000 years ago and i would bet dollars to dognuts that no one evgfer filled the thing with super

that being said - Scott knows more about this engine than everyone so i'd take his advise

 

Ping is also known as detonation and knock and can most definitely cause damage . It the old days of Iron blocks and pistons you might have survived , but not in a Aluminum piston and aluminum cyl world . If severe enough you can crack a ring land , beat on the bearings till you loose oil pressure and toss a rod . I have had two bone stock cars in the shop this year with holes in the block .


Without being there I cant say if he is severe or not , but with out the pros and cons being said he cant point the finger if there is a failure either

 

correct , if it does not feel right ... Tow it .. Sorry
