[DeTomaso] ROTELLA motor oil

[pantdino at aol.com]

I believe the term Rotella applies to multiple oils.
If you are referrring to Rotella T 15W-40, that is a gas / diesel oil that has much more ZDDP than most SM-rated gas-only oils.

>From what I read on bobistheoilguy. com, the question of ZDDP is actually pretty complex and even some oils with the SM designation have adequate levels of ZDDP, which should be about 1000 ppm or more.  

I bought a bunch of Super Tech 15W-40 at Walmart because it is SJ rated.  Basically with each "upgrade" in letter designation they take away some ZDDP.
You could check your Walmart if you have one near you to see what it is rated these days.

ichael,
 
What oil pressure do you see on cold stat up with the 20/50 weight? The 20/50 is 
 bit viscous especially if you are not concerned about winter usage, unless 
our engine is designed with tolerances for it or little tired. 
 
Virtually no legal for road use oils have enough ZDDP anymore, certainly not 
nything that meets the API std for SL or SM designation. Most elevated ZDDP 
ils are now sold as Racing Oils for "off higway use"

ersonally I use exclusively Bradd Penn (what was Kendall Green Oil) in all my 
ports cars. Penn-Grade 1 oils have a “typical” 1,500 ppm Zinc (Zn) and 
340-1400 ppm Phosphorus (P)

ther brands which are reportedly high in ZDDP are;
 
Valvoline VR1 Racing, 1300ppm Zn and 1200ppm P
Shell Rotella T 1400ppm ZN and 1300ppm P
Pennzoil 20/50 Racing 1960ppm Zn and 1800ppm P
Quaker State Q Racing 2000ppm Zn and 1800ppm P
 
The alternative is to get some fo the ZDDP additives to add to a regular oil.

 I need to change my oil, I've used Mobil 1 a few times but always seem to go
 back to my old favorite Castrol 20-50. Always open to new things and have
 followed the Rotella comments on and off, if I were going to try it, what
 weight? Does this have ZDDP? Winter usage is not a concern. Michael
