I have read several threads where members recommend using ZDDP in the oil. Got a new Hot Rod mag today, saw an add for Lucas products. They advertise an oil called Hot Rod & Classic Hi-Performance motor oil. They claim it has the high levels of zinc needed. Carry 10w-30, 10w-40, and 20w-50. Anybody hear of this and what opinions do you have? I am new to the use of ZDDP, so I appreciate any input. Thanks, Michael
I'd go with ready mixed oil...alot of new oils have calcium mixed in for newer engines and pretty sure this counteracts the zddp. ready mixed zddp is cheaper..more so if you can get it in dino oil...edelbrock? summit not sure if lucas is synthetic or dino but amsoil has one called vrod
Why flush money down the toilet buying oil additives and still not knowing what your zinc levels are? Valvoline VR1 is rated 1400 ppm which should be enough for almost any street driven car. Here's the product info: http://www.valvoline.com/pdf/vr1_racing.pdf
The Summit Racing oil I used states it has 1800 ppm of zinc in it, lightest weight they had was straight 30 weight tho.
Although Valvoline claims the VR1 contains the proper amount of zinc and phosphorus, it's been tested multiple times and their numbers are generally a little misleading. I wouldn't run it if it is zinc content your looking for. Their "Not Street Legal Racing Oil" on the other hand is what it is represented as. It has the proper amounts of zinc and phosphorus (.14/.13), and also has moly as an additional anti wear additive. However since it has a low detergent package, Valvoline only recommends 500 mile oil change intervals.
Lots of wisdom on this topic (Re: ZDDP) Dear Michael and V-8 Buick fans, If you search the board a little you'll see a lot of discussion on the best oils for your precious engines. I always refer people to this posting by Jim Weise: http://www.v8buick.com/showthread.php?222499-New-Oil-tech There is a lot of wisdom in it and raises issues that certainly weren't obvious to me. This current thread on when to use synthetic oil has information on ZDDP as well: http://www.v8buick.com/showthread.php?251589-When-to-use-synthetic-oil. There are lots of ways to get an oil that has sufficient ZDDP in it. For many fellows on the board the final choice is driven by what is locally available. Hope this helps, Cheers, Edouard :beer
I run quakerstate defy. Conventional, but its made with higher zddp levels and old cars. I also bought a 5 pack of those zddp bottles off ebay. All is good so far on my 2gen 350 build
