How much zddp
So down the road when I do get to crank my engine with solid flat tappet my plan is to use lucas brake in oil that is supposed to have 3600 zinc. Then switch over to a 20w 50 synthetic with somewhere in the 1300 to 1400 range of zddp maybe amsoil will have that or mobile 1. Have sort of convinced myself synthetic oil is better then dino. But lucas has a dino oil 20w 50 that's 2100 zinc. I'm I placing to much importance on zinc and is there a point that to much is a bad thing.
Re: How much zddp
Why not use the break in oil...because it is for breaking in new engines. Unless the label instruction says to add an extra ingredient, why would you?
Every oil company info I have seen tells you NOT to add anything to their oils, assuming you have selected the correct oil for the purpose at hand.

VR1 synthetic is available in 20-50
i think it's important you use an oil that's good for flat tappets, if you have flat tappets
tho the exact% of Zddp it has in it IMO, is less important.

Re: How much zddp
After initially running the engine in with a proper break in oil (the Lucas break in is good), you're going to want a oil with at least 2,000 ppm of zinc for a flat tappet setup...whether it's synthetic or conventional. Forget about any snake oil additives and just use a properly formulated oil. Valvoline VR-1 and Red Line are two brands I can recommend but there are other good ones. The 20W50 thing is puzzling, though....

Re: How much zddp
For all our flat tappet cams, we recommend PennGrade 1 Break-in oil, then switch to PennGrade 1 Partial Synthetic High Performance Oil.

Re: How much zddp
No not interested in adding anything to oil just plenty of zddp in the oil after I switch away from the lucas break in oil. Only thing I have seen mentioned about zddp it can be corrosive so maybe very high amounts not so good. Lucas makes several regular mineral oil that are 2100 zddp then what they call extreme marine is just over 3000. Then they make a strait 70 weight probably for top fuel engines that's 5600 zddp. Mobile 1 has there classic car and hot rod oil, amsoil has there Z rod that are fairly high in zddp.

Re: How much zddp
Where can I get penngrade oil ? While your on here can you make a solid flat tappet cam that has the LS firing order and is it true that firing order is supposed to be better for the crankshaft and bearings ?

Re: How much zddp
Penngrade is also available through Summit. Penngrade also sells a decent GL4 90W gear oil... Reasonably priced as well.
I've always used Mobil 1 15w50 synthetic in all my flat tappet and air cooled (yard/motorcycle) engines. Have used it for decades. It's the only Mobil 1 grade that has a good ZDDP content at 1300 ppm. Can usually pick it up at Advance Auto. 5 quarts with a Mobil 1 filter is often on sale for around $35. Can sometimes find 5 quart jugs at Walmart for around $28.

Re: How much zddp
Competition sales in north dallas area 12.5 miles south of me I can live with that. Summit racing put a big warehouse/store in Arlington tx about same distance from me. Almost everything I have bought has been with summit.
Re: How much zddp
BTW, the PennGrade 1 partial synthetic has a zinc content of 1,500ppm, and a phosphorus is around 1,400ppm.

Re: How much zddp
There's a few really good "Off the Shelf" oils out there. I don't recommend them, because the large companies have a history of changing an oil's formula, without ever telling anyone. There's a much smaller risk of that happening with a "Not for on-road use" oil.n2omike wrote: ↑Sat Feb 29, 2020 12:27 pm I've always used Mobil 1 15w50 synthetic in all my flat tappet and air cooled (yard/motorcycle) engines.
