The article I quoted was with an automatic, as the Jaguar XJS has a 3 speed GM Turbo 400 automatic. Get on the highway, slow down somewhere to 40 mph, then punch it till it gets to redline. Do that a few times.

I actually do that almost every time I get on the highway, lol. When I pulled the heads a few months ago, the pistons, combustion chambers, and valves were very clean.

Oh, whoops, I just need to pay more attention. I feel retarded. Thanks.

I tune my car up frequently. : )

Now, I just asked my dad if he'd ever heard of it, he said no. I told him what it was, and he said that'* a good way to ruin an engine, I guess you just shouldn't do it all the time. I just think he'* crazy.

I have a 216k mile engine that I redline 5-10 times a day that will prove otherwise. I bought it with 61k miles, so that'*...155k miles of wide open throttle runs.

I also have compression test results to prove otherwise. Wide open throttle won't kill anything but your fuel economy.

My dad used to say that too. That was when I was 17 years old and didn't know anything about cars.

Here'* what your cylinder head will look like if you drive like a grandma:



Caked with carbon all over, because you never create enough heat in the combustion chambers to loosen up all of that crud.

Ever hear of seafoaming your car? Does the same basic thing.

That'* horrible. I need to prove my dad wrong. that is, when I get a Bonneville, a month to go! God, I can't wait!
