Kevin Rutherfrauds $200000 Signature glider truck has complete engine failure!!!

good info, thnx. it does sound like you are getting some documented value from yours. I still will state my case that if we both start with fresh oil, me no bypass, when I change my oil at 15k, my oil is going to be cleaner then, before the change yours may have been cleaner. Bottom line, dumping oil in a pan and putting fresh in works better than any filter, know what I mean ? if the goal is clean oil. if the goal is save money, gotta have a comparison like cowpie to decide.

 

I see as keeping the oil at, say, 80% vs oil starting at 100%, and dropping to 40% at next service. Of course this also depends on engine, condition, service, and hours/miles between changes, etc.

 

I don't think there is one perfect answer, but here's the theory:

If I drive 15,000 miles at 55mph and another fellow drives 15,000 miles at 75mph -- he'll have 36% fewer hours, but do you really think his oil will be cleaner than mine? Which one is going to have more soot? more fuel dilution? Who's oil ran hotter (think of the oil temp inside the turbo at 3psi vs 25psi)? Who had more blowby (which introduces acids to the crankcase, lowering the base number)?

Again, I don't know for sure, but it seems plausible that fuel consumed would have a higher correlation with oil breakdown than either miles or hours.

 

Certain of which? Cowpie when he drains his oil at 25k , could send off a second sample of oil out of the bottle and the lab results would be hard to tell apart. Him changing it at 25k is what he is comfortable with. And there is nothing wrong with that. The CAT we rebuilt at 1.5 was running a bypass filter, and draining at 100k . It blew a head gasket, planned on doing it while it was down, CAT saw the liners and bearings . They were saying fix the gasket and run it. But we were pulling it down that far , just do the whole 9 yards. No telling how far she would have ran. There is one member here that has over 2 million miles on his engine with out rebuilding. And this was before KR had a radio show, so he had no part of it. His ideas have been around before him, he just has a show (now) to tell people about them . And there is no silver bullet that works for everyone.

 

I meant are you sure it's an improvement. That's KR logic to say how clean the engine is. You would have to know what the engine would have been like without the bypass, and the cost difference to know if it's worth it or not.

 

in the 90's Cat had a buy back program on their engines
only thing they wanted to know was how much fuel had been used

 

No, you just have to know what a normal 1.5 mil mile motor looks like when torn down.

 

I know not many people here trust PP anymore, but I read recently about a method they use for cleaning out the old oil in preparation for switching to synthetic oil from conventional. Guess they use some kind of solution to run through the engine and it breaks down and removes all deposits and gunk and such. Then do the oil change. Makes me wonder if there's any real benefit from this procedure. And doing it just as a preventative maintenance program, like say, every 150 or 200 thousand miles.

Then again, how many people are going to trust him enough to change your oil?

This is more directed at the procedure itself and not the guy doing it.

 

Sounds like what you can do with a quart of ATF if you are so inclined. Probably PP has rebranded some ATF as some sort of magical engine cleaning solution for the switch to synthetic and they only charge 10x what a quart of ordinary ATF costs. What a waste of money and time. Change the oil and not worry over a non-issue is how I look at that. Never going to get all of the old oil out and little mixing of old with new is not going to hurt the engine.

 

Magic is an important ingredient to any impossible task. Add in a little wishful thinking and unproven claims and it's a sure thing. You're obviously not smart enough to know better LOL.
