zinc additive with roller cam?

383, aluminum heads, roller cam yada yada. Any reason to add zinc or use oil such as Rotella?

Re: zinc additive with roller cam?

The GM engineers are looking into asking for more zinc in current oil formulations due to the number of failures that occur while under extended warranty on roller cams.



Zinc reduces wear on all metal to metal contact points such as the rings and oil pump. It can only prolong the life of the engine not hurt it.

Re: zinc additive with roller cam?

The problem is zinc does not work well with some detergent oil formulas.

540RAT is a poster who tests oils and found Lucas synthetic with zinc to give the highest psi protection.

I think he posted in the "Performance" forum last time.

Lucas 10W-30 synthetic :

Have had great results with Mobil1 full synthetic, as well as Valvoline VR1 10/30-10/40 non synthetic oils.

Re: zinc additive with roller cam?

I do not like to add any additive to my oil. Find the correct oil for your application. I was using Brad Penn, I just switched back to Valvoline VR1 10W30 conventional oil Silver bottle).

Ditto that. Additives poured in by the consumer upset the balance of additives the the oil producer put in the oil at the refinery. Find the right oil. You only have to change it once a year (if even that) unless you're daily driving your Camaro.

Re: zinc additive with roller cam?

I agree with the posts above, additives added to your oil may or may not be compatible with your oil. Find an oil with the additive package that works best for your application. I am also running a 383 stroker with aluminum heads and roller cam and have had very good results with Rotella T6 full synthetic which contains higher levels of ZDDP than most motor oils on the market these days.

Re: zinc additive with roller cam?

The reason we have to buy oils "for racing only" is because zddp and phosphorous levels that protect tend to foul catalytic converters.

So Valvoline VR1 and Lucas synthetic are two of the "racing only" that work well.

I also know a few people running Mobil 1 with low levels of zddp that are fine.

I guess it depends if using zddp helps you sleep better.

"For Racing Only" oil will NOT hold up to a 3,000 mile oil change interval as well. "Not legal for street use" usually means the oil could/will damage catalytic converters. You have to read the bottle carefully these days.

Re: zinc additive with roller cam?

Diesel oils have had the ZDDP reduced also. Diesels use catalytic converters with Diesel Fluid to control issues. ZDDP has the same effect on those cats as automotive cats.

As much as I don't like the anonymity of 540RAT, his latest test has pointed out the fallacy of high ZDDP oils preventing cam wear. Oil manufacturers have turned to other additives to replace the ZDDP. Have your cam nitrided. It will survive any oil. Nitriding is added insurance but not necessary if you use a good motor oil.

Re: zinc additive with roller cam?

I use Shell Rotella 15w-40 with a bottle of the OLD EOS. And then after a few fills of that, I switch with Castrol GTX 10w-40 with a bottle of EOS. Both are conventional oils. I don't like using diesel oil for too long cause of the high detergents in it. And yes, I am running a roller.

Re: zinc additive with roller cam?

Thanks guys. I have a case of VR-1 and 10 qts of Rottela (and a 7 qt pan). Thinking I'll use up the VR1 first. As far as driving, guessing 300 miles or so per month.

I told Hagerty's 5-5k per year.

Prepare to be the center of attention when you drive a first generation Camaro. You will be gawked at. Grown men & women will coo like children when you drive past. Children will scream like babies. Dogs & cats will get along. Does it get any better?
