Add to that short list Pennzoil Racing Oil, which is Dino oil. My old
standby, Kendal GT-1 Racing Oil, has been drastically reduced in zinc and
phosphorous. Do ***not*** use it. I will be switching to Pennzoil RO. Shell
Rotella-T is scheduled to have its zinc and phosphorus additives reduced in
2007 and reduced further in each succeeding year. Can we all say, "EPA wants
our older technology engines DEAD." Most true racing oils should stay
unaffected by the EPA lunacy.
EPA claims the zinc and phosphorous additives will get into the cat and
corrupt it. That can't happen if the engine isn't burning oil. Anybody ought
to be able to figure that out. If the engine is burning oil, then it needs
to be fixed. But the way modern engines are built, they use no oil. 29
July - 8 Aug, my Trans Sport used 1/3 of a quart of 10/30 Mobil One going up
to Eveleth, MN, 1825 miles, at 5500 pounds GVW, and no oil on the return
trip of 2312 miles at 4200 GVW. 22.5 MPG going up and 23.5 MPG for the
return. The EPA is just plain nuts and uses VooDoo for science.

Subject: Rotella-T
Car Craft mentions Shell Rotella-T in an answer to a question in their
"What's Your Problem" tech section, Sept. '06 issue.
The question is titled "Valve Clatter", in relation to valve train noise.
I n the answer, Car Crafts Jeff Smith mentions the lack of zinc and
phosphorous in current oils, pointing out that a bottle o anti-wear
additive is essential for cam break-in. Further, he says: "But the
problem doesn't stop there. Many cam companies now suggest using engine
oils with higher levels of zinc and phosphorous for engines equipped with
flat-tappet lifters. Shell Rotella T is diesel- engine oil that offers
these increased antiwear additives and is safe to use in gasoline
engines. Another alternatives is using one of the high-performance oils
from Quaker State, such as the Q racing oils , which contain higher
levels of antiwear additives and can be used safely in street engines.
The oils cost a little more, but they may prevent a flat-lobe problem
down the road."
I just thought that it was interesting, in light of our discussions of
oil, zinc, and phosphorous some time ago.
On digest mode, so I'm a little slow...
