Oil with high zinc content
First off, I want to state that this is NOT a "Which oil do I use lol" or "Synthetics are bad?!" thread. I've already determined that I'm going to use synthetic Amsoil 20W-50 on my blocked-OMP engine and premixing Klotz Techniplate R-50.
My question is this: after searching the forums, I couldn't really find any straight answer about The positive/negative of zinc content in the oil. I'm looking at 2 Amsoil 20W-50 oils, a regular one and one labeled "Z-Rod". The Z-Rod is described as "containing a high-zinc formulation that prevents wear on critical engine components and a blend of rust and corrosion inhibitors for added protection during long-term storage." Does a high-zinc formulation have any adverse effects on the components of the rotary, or negatively affect the way it performs? Thank you for your responses! ~Anthony |
Still looking for informative responses!

Really?! NOBODY has ever had this question before?

My last oil change i switched to brad penn 15w-40. The added zinc helps greatly with lubricity especially when oil pressure drops in your system like when in a sustained high g corner. All the racing oil we use at our shop has a large concentration of zinc for this very purpose. The only downside that i have heard of is reduced catalyst life . . .

This thread should help answer your question..

Supposedly the only drawback of high zinc content is if the engine burns oil then it will reduce catalytic converter life. That is the only negative I have read.

Great read, thank you! I don't run a catalytic converter, so that won't be a problem. Looks like I'll go ahead and purchase the Z-Rod one.
Thanks for everyone's input! |
I run Brad Penn race oil. and here is some good reading.

Shouldn't be using high ZDDP oil to mask issues with your oiling setup. Idemitsu determined that ZDDP is detrimental to high load operation in rotary engines for reasons listed in the above article. |
A good race oil is not going to be bad for your rotary. 98% of the off the shelf conventional oils out there are designed for emissions and there is alot of lubricating properties that they have reduced and completely taken out of current conventional oils.

Nope. Just gas. Brad penn dont get along with E fuel from what i hear.
Nice try I used BP but now im going to run E....Dunno what to use now. |
Their is others out there that are good like BP but safe for E fuel. Just search synthetic race fuels.

P>S with the boost leak fixed we did 557 @ 15lbs until you hit more than 28lbs the turbo is not at its full poential [/QUOTE]

Damn dude thats alot of power for such a big turbo at low boost. what is your peak tq timing at with the E fuel? Just curious cuz im debating on switching to E.

Ohh gotcha ah hahahahaha. Man you pay attention well lol.
Yea I only have one station in town for E85 so ive been debating on it. Also i have only been running the BP oil this last year with good luck. I hear pro's and cons on every oil out there anymore. But if i do go E fuel I will for sure have to ditch the BP. ANyone know any other good oils like Bp that is more compatible?

Theres tons of stuff on the market, no doubt. Im just sided to the "green stuff". I know few "ins and outs" about it that i would probably never find out about any others. My opinion, nothing else. The combatibilty issue just sucks.

Do you have any evidence to refute idemitsu's claims that run contrary to what you just said? Or did you just regurgitate some blanket statement from that thread without reading the sae paper?
