I only put full synthetic oil in everything after break in. Its all nascar, NHRA, & commercial aircraft use in their engines. Commercial aircraft run the oil with no changes on the turbine engines. Just topoff daily from normal consumption. Tells me alot about how good it is lubing and withstanding the high temps

I've heard enough to get the Rotella out of there. I'm not going to change the filter until I winterize though. I guess one qt. of Rotella mixed with better oil won't hurt for awhile. As far as other oils, I have my favorites but that topic has been beaten to death so that's all I'll say! No more Rotella though. Idiot at the store should have known it was a truck oil but seemed to think that it was for performance gas engines.

Can I ask one more question plz? Is there any reason to not run a high zinc oil in a roller engine? Without going over everyone's oil preferences, I bought Kendall 20w50 to finish the season with. It says it has zinc added. I haven't put it in yet but the Rotella is out.

Just one remark I want to make to you about Rotella and the opinions regarding roller anything. Diesels like Cummins, Cat, MTU, JD, Volvo etc, etc all run roller everything, cams, rollers on the rocker arms, injector plunger rollers, etc, etc.
I can't tell you whether or not it is good for your gas engine but as far as being good for rollers it is a great non synthetic oil. The one person with foaming issues, it might be because it is a high detergent oil made for slower turning engines, the extra rpms might whip it into a froth, which then would be bad?
We at one time ran many trucks, into the thousands of units we used the Pennzoil synthetic toward the later years, the only advantage we ever saw was we could double the mileage between oil changes.
As far as wear went 15k on Shell Rotella, 25k-35k on Pennzoil sometimes longer but both showed the same amount of wear for the overall miles. The synthetic saved us labor plus a set of filters so our costs were down a little even though the oil cost more.
