I've spent my spare time the past three days going over zddp and oils to figure out there is limited availability on specialty oils locally. I ended up buying 20w50 red line oillfor my MY90. After tax was $150 for a case of 12. A bit pricey I thought, and that was after he gave me a buck per quart off!!
I may pick up some mobil1 for the truck and buick though. Thanks for the tip, and rebate link as well.

Thus the Kibort. Mobil 1 is 1200ppm & 1300ppm. Pretty high.

Torco TR-1 or SR-1 is probably the highest. 1550 & 1600 or 1700.

amsoil is right there too.... but you missed the main point of my objection of mobil 1........ viscosity breakdown. pretty serous at 220 to 240F track temps. i also think the anti foaming characteristics of the amsoil (and a few others) is quite superior and might be the reason i dont see much oil in the intake or other "oil related issues" as compared to most. just an observation.

definitely going to grab some mobil 1 for the tow vehicle though!!!

No plans to track or hit those temps

I'll never use M1 in my cars a again, my Audi A6 2.7T started to experience low oil pressure alarming, getting close to oil change interval. Never happened when I used other oils. Did the oil change used Rotella T6 and no more low oil pressure light! Just did a change in the Cayenne, used the Rotella in that, engine sounds quieter, may be my imagination but after the Audi incident I feel better without M1. Just wish the T6 was available in 20w50. It's either Amsoil or Brad Penn in the 928.

should be no issue then!!

I use vegetable oil.. Lubricates like a dream and has another use when I change the oil.

Lubriguard 15w 40 has been the dino oil in my 928 for the past 13 years. The PO turned me on to it when I purchased it. I also used it in my Spitfire, and 72 Datsun 240z, used fleet wide in our diesel trucks. Check out the testing site.

Go to middle of page and click on " sample set" to see it compaired with other oils. Can be purchased at Auto Zone.

You may be hitting 220 and not knowing it.

Do you have a second engine temp gauge?

220F is easy to hit if you've got a loose fan belt, low on coolant or simply on a hot day in traffic. Install an accurate gauge and you will see.

I would not use Mobil 1 no matter how cheap.

Conventional Valvolene VR1 Racing 20/50 is superior (high zinc for our motors, anti foam)it's the #1 racing oil and very easy to find affordable.

Regular old conventional Valvolene oil was found to offer much better metal against metal protection than mobil 1 synthetic in an independent test.

Mobil 1 was one of the worst in the test.

He better be hitting 220, thats how you keep water out of the oil.

220 isnt that hot..the oil brings a lot of block heat down with it.

Coolant temp != oil temp.
