which oils affected by removal of zinc?

[LC2]

Royal Purple

I use only Royal Purple and noticed it was not on that list.

So I called the tech line and the guy said because it is NOT a "SM" oil, it is fine to use on a flat tappet cam as is with NO additives.

Chevron Delo 400 15-40W Zinc 0.148 Phosphorus 0.136 Straight from their website.

Stay away with oils that have the star burst symbol on them and you should be fine, I use Valvoline racing in mine, 4 and1/2 qts 10-30 and one 20-50. just my formula.

I'm glad I started this post. Maybe the reason I'm replacing a motor is because I used Mobil 1 15w-50. It says "none". Live and learn, right? Tim

Tim,
I doubt that is correct. Even the latest, low Zinc oils have something like 0.06-0.08% Zn.

Im surprised there's not a class action on this. Ive told other car guys about this for 3 years now....they just scoffed. I saw a guy who I told and he said, "Youre right, a buddy of mine just wiped out a $28000 rat motor in 100 miles." There should be a warning on label. Id like to see the gov sued , not the oil companies. I know, gov is immune. At least theres agreement that its the lube....I argued that on this site 3 years ago.

Stock up on the GM # 1052367 , EOS (engine oil supplement)


"Specifically formulated as an engine assembly lubricant. EOS provides outstanding protection against run-in wear and piston scuffing as well as run-in camshaft lobe and lifter scuffing resulting from insufficient lubrication."

Where did you get the info on the amount of zinc in the oils? Is there a chart somewhere?

All the info you could possibly stand, VOA's and much more:

Hughes Engines Inc. Extreme Pressure Lubricant?

Anyone else heard of this? Anyone use it in our cars? The sales pitch sounds promising, but is that all it is, a sales pitch? I might try it if I'm not the only one.
