Forced induction effectively increases the compression ratio of the car and makes detonation more likely. The higher octane fuel is necessary to prevent detonation under boost. You can probably run

Hey Dan. You shouldn't need to run premium in your Roadster since we did your valves--if you are still getting pinging, we should check your timing as I don't remember if we did that or not. I though

Most turbo cars require premium. Turbocharging puts a lot of heat and pressure in the engine and that can cause detonation. That will blow up a turbocharged engine real quick. Modern turbo cars will

Generally speaking, because of the turbo boost the effects of pinging are far more dramatic. You'll hole a piston far quicker in a turbo engine than a non-turbo engine. That said, most have a knock s

Luckily it's a Subaru, so he can run regular gas without it blowing up any sooner than it otherwise would've ;) Both my Subarus ( 2000 Legacy and 2003 WRX ) blew their headgaskets before 60,000 miles

With some vehicles (normally-aspirated as well as blower) you will hit a point in the engine-protection strategy where the resultant reduction in spark timing, etc. ends up costing you big-time in dr

I'm not suggesting you use it unless you need it, but I'd note that the $.20/gallon extra for premium is, at current $3/gallon gas prices, a smaller increment as a percentage of the total price than

Unless of course, using premium means you actually use less fuel for the same distance. Pretty much all modern cars use a knock sensor to measure fuel octane, and advance the spark accordingly. More

That is correct. In fact higher octane pump gas often has slightly less energy per gallon than regular. High octane only means that it is less willing to detonate. The adjustment that the ECU makes w

Yes. Newer turbo cars have water cooled turbo housings which don't get as hot and will circulate water after the engine is stopped to continue cooling the hot parts. So they are less likely to cook t

What you don't want to do with a turbo is to wing the gas before you shut down the engine. Just let it idle for a few seconds before you shut down. When you shut off the engine you are killing the o

Depends on the car and the turbo. First, many turbos are water cooled. They don't have any cool down problems. Just shut the car down like a normal car. Oil cooled turbo units, those can require a bi
