read this and be warned about your motor

[mptoledo]

Adam,
I know I am not Jake, and by no means pretend to be in the same league as him.

With that said, what I have read and its been quite a bit, is that you are basically prewashing your lifters and such with the stuff for about 5 to 30 minutes, not nearly enough time to break down the real oil. Most of the experts, including"little bastard" then suggest changing your oil immediately after, and some have suggested changing your oil again in about 500 miles. Unfortunately I have just put in some pricey castro sytnec and may wait till I am ready to change it out next year. The reason they advise me to change my oil is that after the seafoam, atf... has loosened the sludge and crap in your engine, you need to get it out quickly or it will just settle something else. the sludge forms when an oil starts to break down(read the following exerpt on sludge).

"Sludge formation begins when the chemically suspended particles of contaminants begin to settle out of the oil. It's a fairly daunting task for engine oil to suspend all the contaminants thrown at it, and any engine oil can do this successfully to a point. Pennzoil, and some other quality motor oils, are able to perform this task more effectively and for longer periods of time. But eventually, if the oil is not changed often enough, a "breaking point" will be reached. This breaking point is either when there are too many contaminants to handle or when the oil's chemical defenses are weakened, and it is caused by two main things: excessive accumulation of contaminants in the oil and chemical changes in the makeup of the oil itself (depletion of the additives and oxidation).

"As more particles are suspended, less of the additives are available to do their job. Knowing this makes it easy to see why too much time between oil changes can be one cause of the oil reaching its "breaking point"."

I understand the concept behind it, but kerosene is a solvent meaing it breaks down oils and lubricants. While it may clean up some gunk and deposits, I wonder how that affects the rest of the internal engine compenents. My thought is it would lessen the oils ability to lubricate things like bearings, camshafts..ect and could open up a whole new can of problems.

I totally agree with the above....

IMO, the solution is an easy one....I would (and i always do-regardless of whatever car i have, and oil i use) change my oil at closer intervals rather than sticking to the dealer recommended oil change interval. This way i know that there are LESS contaminants, and lesser chance of sludge formation.

Dino oils have a recommended oil change interval of 3k miles (which was the common accepted "rule" for decades)....With the advent of better Synth oils the "average" oil change interval is around 10k miles ......I personally change Synth oils NO MORE than 7k miles this way i know that i am always below the recommended interval.

BTW, engine design could, and can also contribute to sludge formation (crankcase breathing design, etc....etc).

Don't forget about the air filter. I almost did. I never thought that would help until I started doing some research.

The warranty company paid for the IMS bearing replacement for Jhandy's car!!!
AMAZING! The bearing was actually bad and the Inspector saw it first hand.

I don't think I want to deal with any more of these Morons... Its just not worth it, it took them 3 weeks to even decide what they were going to pay for.

Thank you so much for your work in this cause/hobby.

Best of luck to you and your Dad Jake.
