Is high octane fuel a requirement for high-compression engines?
The problem is, the crossfire isn't just high compression, I believe its supercharged as well. Forced induction motors like octane - the high pressure, high compression, and most importantly high combustion temperatures make you more prone to detonation. There are enough electronics in the engine (knock sensor for one) to realize that something is amiss and it will usually pull (retard) engine timing to compensate as a safety measure. As a result, you will lose horsepower - a significant amount. However, it can only reduce timing so much. If you're running low octane fuel and push the car hard enough, its conceivable that long term damage can still be done. bottom line: manufacturers recommend high octane for a reason.

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
