Motor Medic

[SPR]

If you're wondering... Treating my Buick 231 with Motor Medic got rid of my lifter/rocker noise.
Maybe I had some junk in my lifters?
Maybe I should change my oil a little more frequent?
I doubt I go more than 2K miles between oil changes, but the 2K are rough miles.

think that would've fixed my lower end noise?

If you figure those are all low speed miles. Every hour is equal to 30 miles. I usually Change the oil in my bronco once a year. I'm sure it's less then 1000 miles but most at pretty low speeds and usually working hard.

Lower end noise sounds scary... Bearings. I thought the 4.2 were built proof on the main bearings.


I change the Toy's oil at least ounce a year and add a couple of quarts during the year. It sure seems like it gets black pretty fast. Maybe I should change it spring and fall.

If you'd run a detergent oil such as del 400 or Rotella t you wouldn't have to use that crap to clean the gunk out.


If there is a next time just replace a quart or two of engine oil with atf on the next oil change and you'll accomplish the same thing as that bottle of voodoo.
