WOT - Even if I run 75 mph on highway?
I do a great deal of Interstate driving down here in Florida - typically going 75 mph. Do I still need to do a regular WOT or will that type of driving keep the carbon buildup down? Thanks.

Going from memory .. maybe slowroll can point some details? The latest NorthStars have low friction piston rings that tend to "clog" and i remember seeing some bulletin about a "cleaner" that is applied through the spark plug holes to keep the rings free and working to their best. The point of the WOT is also to that end. Keep the rings free and working to their best and it is one of those little things an owner can do and it is recommended by Cadillac's Power Train Dept Design and Eng - dont remember if the recommendation is "official" or not, but it is there. The WOT procedure, directly provided to this writer by a GM/Cadillac Engineer working on the NorthStar project from the onset is posted in the FAQ section ... |

GM has used low tension rings since the 80's. The problem is (I started with Olds) The Olds 4 valve per cylinder V8 & L4 have such a high operating range they have some concerns with the low engine speeds automatic transmissions cause, they were built to rev up and down. The rev'ing helps keep the the engine from carboning up, including keeping rings free. I admit it is strange the GM never offerred manual trans for the 4.0-4.6 when they knew from the start these engines required some exersize that they would not get at 55-65 mph speed limits.

I've always done WOTs when the engine was thoroughly warmed up. Are there any advantages/disadvantages to doing it with the engine cold? I would imagine that it would be bad to do it cold, but then again I would have imagined that doing WOTs - warm or cold - would have been a bad thing.
