    07 RT El Cheapo Oil Change

    What I had laying round. 2 qts Castrol 20-50 4T Mineral. 1 qt Mobil 15-50 syn, 1qt Castrol 4T racing 10-40 syn, Pure one PL 10241 filter. Did have to buy the 4T racing for $6 on sale though.

    Oh great. Now you've started a "What can happen if I mix mineral and synthetic oil?" thread!
    Not to mention THREE different weights!

    I think that you have found the perfect mix and yes I am 90% serious. A 2 part mineral to a 2 part synth is ideal.

    Extra Bold!


    I've often wondered what would happen if I just dumped some Rotella from WalMart into my RT. I'm kind of sick of the $50 do-it-myself oil changes!

    My take on that.... if Rotella is good enough for $20,000+ diesel engines, it will be just fine in my RT.

    New oil is better than old oil. Clean oil is better than dirty oil. Good oil is better than bad oil. Some oil is better than no oil.

    I just looked on my garage shelf and found:
    1 & 1/2 qts of Castrol 30W
    1 & 1/2 qts of BMW 20W50
    1 qt of Castrol GTX Syn Blend 5W20
    3/4 qt of Castrol GTX 5W30
    1/2 qt of BMW 10W40
    1 qt of Castrol Syntec 5W40

    If I mixed the together what would I have, besides a little over 6 quarts of a slick liquid? What would I feel safe using this liquid in, nothing.

    My own personal experience with mineral-synthetic blending (and I know it proves nothing ) is that I had a Castrol synthetic blend oil change done on my Dodge pickup that only had 17,000 miles on it, and right after, the cam gear disintegrated causing the need for a new engine. Like I said, it proves nothing to you all, but makes me afraid to do a blend in any of my engines.
