    I purchased a car a few weeks ago and it was on empty when I left so I filled it up with the lowest gas grade 87. When I had time to review the manual it said that it requires grade 89 and it started to run a lot smoother so yesterday I refilled with premium grade 92 @ Costco. I had the car checked out immediately and was assured that it was in great mechanical shape. This morning the engine light came on and I was wondering if the original lower grade gas could cause this reaction until it has totally gone through the tank & engine.
