Re: 90 SPG Fails CA Smog Test - Thoughts? Posted by morgan [Email] ![]() ![]() ![]() In Reply to: 90 SPG Fails CA Smog Test - Thoughts?, Randy Thatcher ![]() ![]() |
we use to have these test here in louisville but no more..
i would always fill up with amoco premium......(almost clear gas)
then make sure the car is hot... drive it a half hour...
then if i fail I change the plugs....
then if i failed again i would switch to mobile 1 synthetic oil..
since the synthetics dont burn...or smoke..
