 Subject: Marvel Mystery oil for lifter help?
IP: Logged
Message:
I have an '88 Dakota 3.9L 4x4, all stock, with 134,000 miles on it,and occasionally the lifters will clatter on cold start up. Clatter goes away after engine is warm. A mechanic said the cam could be damaged if noise continues. He suggested 1 qt. of Marvel Mystery oil at next oil change.
Is this a good idea, or will the mystery oil loosen a lot of crud and create more problems?
Suggestions/opinions?

Use lucas oil stabilizer, oil alone is not enough... You should notice higher oil pressure and they claim that it creates less friction and less wear on the motor. I use valvoline 20/50 w/ a quart of lucas at every oil change...

I ran 1 qt of transmission fluid in my truck for 500 miles, changed with all oil, ran that for 500 miles to flush, then back to changing and running with all oil.
This restored my bad gas milage from <15 on highway to 23 mpg on highway with transmission fluid in the oil.
I later opted to take my truck to pepboys (other shops may do the same) and paid $80 for their engine flush service. They flush warm cleaning solution in oil filter port at 42 PSI and vacuum it out pan. This includes proline oil and filter change (pepboys brand). This is a safer and faster way to go thans transmission or marvel.
Those on here will say that this will knock lose sludge and cause it to trap in the oil filter. that may be the case, but not happened to me. Keep a close eye on your oil pressure.
I was told they removed alot of sludge from my engine this way. I've posted this story many time and will probably post it more. I plan on doing this on a yearly basis. You can upgrade to name brand oil and filter if you want for an additional charge at pepboys.
I've since switched to synthetic oil and use seafoam at every oil change (www.seafoamsales.com). 1/3 can of seamfoam goes into my throttle body for the air intake system, 1/3 in my oil for sticky lifters, and 1/3 in the fuel tank to clean injectors.
I have a 95 CC 4x4 w/ 3.9L auto now with 155k miles. I get 17-18.5 mpg city and up to 25 mpg highway (have a tonneau cover). I recently made a trip from atlanta ga to raleigh nc and got 20.5 mpg driving up to 90 mpg with an avg of 85. At 85 mph i run 2200-2400 rpm.
