Yet Another Zinc Oil Question #5274345 11/22/19 09:07 AM

Okay joined today because I've had about enough of reading about flat tappet cams and what engine oil is suitable. First thing, is I've an old Y-block Ford engine with solid lifters. It was overhauled some time ago and has excellent oil pressure and flow. Valve spring pressures are not radical, stock cam etc. For the moment, let's leave aside the question of whether ZDDP or elevated zinc/phosphorous is even necessary.

What I'm looking for is a readily available gasoline engine rated motor oil in 10w30 with a normal oil change interval of 5,000 miles or near enough, and doesn't cost $17 a quart.

For many years I never paid any attention to it. The Zinc Question that is. Always been pretty good about oil change intervals. After a bit of reading on the subject, I then switched to Rotella T for a while, 15w-40, and it's a good oil - but after installing a new oil pump and gauge it looks to me the engineers got it right, the lightest viscosity oil that maintains good oil pressure when hot will also have good flow. Rotella has lots of "detergents", which is good, but I'd just prefer a modern high quality oil with a little extra zinc for peace of mind, and an additive package designed specifically for gasoline engines that has sufficient detergents/dispersants anti-foaming agents, corrosion inhibitors, blah blah blah. Maybe there is a "Diesel" oil that is also S (spark engine) rated, I dunno. I don't want to make a career out of this.

I have VR1 10w30 dino oil in it now. Not outrageously spendy, has Zinc, but it is "racing oil" and per a phone call with Valvoline is only good for 3 months/3000 miles. The 3000 miles doesn't bother me, the 3 months does. It doesn't have an additive package designed for extended oil changes. I think once or twice a year is fine, I don't drive it that often.

The problem seems to be that simply because a motor oil contains Zinc, that doesn't necessarily mean they are using a good quality oil to begin with. Marketing. "Break-in" oil is not really a good choice, and additives in a bottle aren't a panacea either, as motor oil is a carefully blended package yadda yadda. I don't want to install oil additives.

I've had it reading these oil threads on the intertubes. I'm just a simple guy trying to do a simple job. When I was growing up we just grabbed a yellow can of Pennzoil and tried not to spill on the exhaust manifold because it smelled funny for a while.

SN rated lubes for pcmo's are gonna have the zinc capped no matter the brand. Find a diesel 10w30 like Motorcraft Super Duty if you want higher zinc.

Others might suggest that the 3 month interval can be ignored (I don't know).

Maybe inquire about Penngrade 1 oil @ $7 per quart delivered: https://www.amazon.com/Brad-Penn-Pe...3&hvtargid=pla-569805718203&th=1


Oops - kschachn, are we being led on a snipe hunt here?

The perfect oil for that engine: Mobil1 15w50 5quart cheap jugs at walmart, easy to get or order, made by a team of know-it-alls, high ZDDP, street qualified specifications, long drain, GM tells Corvette owners who race to use it.
https://mobiloil.com/~/media/amer/us/pvl/files/pdfs/mobil-1-racing-product-guide.pdf
The PDF file there has the zinc content info on an infographic near the end.
The SN qualification says its for street engines, long drain synthetic too.
If starting in cold weather, like below +10F, then use Mobil1 0w40, very suitable for you as well.

I did see you "want 10w30" . If cold flow is needed, the Mobil1 0w40 is cheap and very effective, replacing old "10w30" out-dated weights.

You do not need elevated ZDDP in that engine. SuperTech synthetic or conventional is light years ahead of what that engine had when new. Been using lowered ZDDP oils in my flat tappet Ford since API SL came out. No problems at 255k miles.

No offense meant, but your question is impossible to answer unless the valve spring pressure rate is taken into consideration.
A good 10w30 might do the trick or a boutique oil might be required.

If I ever pull apart one of my classics again I will stab a roller and be done with it.
Here is a great post from the C3 Corvette Forum.

I second that. Zinc is around 1200 ppm.


If you want the job done right......do it yourself.

You're probably right. But, it's also at least possible that you're wrong. If it's all the same to you, I'd like to use an oil containing zinc, even if I "know" it's not necessary. It won't hurt anything, other than maybe my wallet. See where I'm goin' with that?

I like that, but is it also rated for gasoline engines? One thing I noticed about Rotella T, it keeps the insides of engines sparkly clean.

I've read Diesel rated engine oils don't contain the anti-foaming agents that gasoline engine oils do - because they don't rev very high. I have to admit I don't rev the Y-block too high either. I replaced the timing gear set this fall and had access to the oil pan. It was very clean, no sludge.

Mobil 1 15w-50 and Rotella T seem to be good choices.

Driven GP-1 10w-30 is semi-synthetic with ~1300 ppm Zn, ~1200 ppm P, ~430 ppm Mo, ~200 ppm B, and is $8.29/qt.

It's the same cast of characters over and over: Shell Rotella T4 which the Shell tech line will tell you is THE oil to use in flat tappet engines no matter that it does not have an "S" rating. PennGrade partial synthetic, Valvoline VR1, Joe Gibbs all recommended by the three engine different builders that rebuilt my flat tappet engines. Take you pick and pick the viscosity that works in your temperature range.

You will get many opinions here. The Valvoline VR1 you are currently running is good stuff. I agree that you shouldn't run it longer than 3k, But 3 months is a crock. If you're only putting 1k per year on the car. You can run for a few years with no problems. I know someone who has a 68 Galaxy with a 390. Rebuilt some time ago to pretty much stock configuration. Runs VR1 with no problems at all.
