rotella diesel oil

I use Rotella-T 15w40 in all my race engines. Good luck with this and always ZDDP with that also.

I have used the Chevron equivalent diesel oil, sold @ Costco, with no issues.

Oh and my 66 Classic 232.

I just buy the best oil with the best wear test characteristics and don't bother with added stuff, it's not necessary and in fact with some oils, it takes you backwards, reducing the oil's effectiveness.
I've not followed the "high zinc is required" bandwagon.

I put Mobile 1 syn oil in my last engine rebuild, have a Xtreme 4x4 cam in it and have over 20K miles on it. Lobes are perfect, rings are doing fine, good compression, burns NO oil between changes, etc. Plugs run clean and free of any deposits, they look like new after over 20K miles.

The Javelin is also running a Comp Xtreme Energy cam and the lobes look like brand new (I had the intake off messing with it and got curious to see how I was in just using a top quality oil with good wear specs with no additives added to the oil by me.)

Science before myth - this guy spells out what I've quietly believed and lived by these last years:

But because many of the big players in the engine area believe the zinc stuff and have huge followings where I have no following at all, you can't win any arguments.
Logic grants you only so much information to use as ammo and once you've stated it you are out of ammo, those who follow the myth have an endless supply of ammo.
So you can't win going against the myth or the big names in engine building.
Science, engineering, doesn't matter as I've found out over the years.  Often I just let myths live on as it's tiring getting all beat up trying to dispel them - but I feel a bit crazy today..........

Oh, and since it works for the others who live by the "zinc is the only thing saving your cam" myth, I'll say it, too -  "I've never lost a cam".
I just break them all in like I have every engine I have ever put together in 40-some years.
The Eagle grew up with a good synthetic and will use that oil until I die or it does, and it's likely to win this one. Those xtreme cams have radical ramps on them and can be a bit hard on things - they are noisy due to the ramp speeds and I'd expect if something was going to fail due to lack of zinc, I should have lost 2 cams by now but one has 6K on it, the other over 20K.

I believe some of what was said . I've also seen cam's wiped in 200 hrs without a break in additive . Read my post on thermostat's . I can quote and post the most recent evidence there is . some will give ton's of reasons why I'm wrong .
but until big cam companies will insure that my Cam and lifters are covered if not using zinc additive ????
"Oil Companies are in business to make money. That’s it. So, they put a product on the market that they feel there is a demand for, and will make them money. As a result, they will say “ABSOLUTELY ANYTHING”, to move that product, which will help their bottom line."
 this I believe above all that he posted . 
 I also read the original post months ago . this is a slimmed down version and missing alot of fails .
Read Chevy blog's .
