Penrite Premium 0W-50 (too much zinc?)

Its not the zinc in the ZDDP, its the phosphorous that attacks grain boundaries as Molakule said. Read the phosphorous column, the "P" in ZDDP. The two figures are usually close, since other zinc compounds exist.

Why not run a proper race oil like Motul 300V? 5W-40 would be perfect for your use http://www.oil-club.ru/forum/topic/8006-8006/
Yes I know it costs a lot more but I think it's worth it in the long run.

I'm running 300V 5W-30 in my own car (3SGE dual VVTi), has done 5500km of everyday driving so far & no drop off yet. Will probably change it at 6K & get a UOA done to see if I can go further.

I don't rate Penrite but their racing stuff looks reasonable for the price but too much zinc?
Anyone used Shell Helix Racing 0W-40 before or have a VOA on it? http://s08.static-shell.com/content/dam/...bricant0w40.pdf

Bad advice Shannow. No more credibility for you! See Molakule's recommendation to not go over 1200 ppm zddp, and your racing oil recommendation fails for a vehicle that sees street use and is expected to last. The 1200 level also explains why Mobil 1 oils don't exceed around 1100 ppm for their entire line of street oils.


Which fake account is this from ???

Penrite (and yes, I've spoken to them) recommend their "race" oils for the street, as they are formulated to fulfill normal OCIs for street driven vehicles...it meets SN (the 5W30 doesn "except" for the ads)...you can look it up if you want, and it meets various European OEM specs from

Main reason for the "race" label is their PAO/Ester "Shear Free" claim...for alky/leaded gas, they reduce the OCI to meet level.

The only thing "fake" around here is your advice. More name calling from you is what I've seen from you on BITOG. Thats your 'go-to' when you're wrong.

The readers need to follow MolaKule's advice, and notice Mobil synthetics for street use aren't overloaded with ZDDP. Its a no brainer for anyone with common sense.

Penrite will recommend anything they sell. And those specs don't address long term effects.

This Mobil ?

who put 1300ppm in the 15W50, and over 1600 (the discussion point here) in their VTwin (which presumably is intended for engines that have camshafts and ferrous metals)

Thats 1200 ppm Phosphorous in the 15w-50, the main point you missed above, and Mobil says that oil is for 'racing and flat tappets', again already mentioned above.

I guess someone ought to tell Mobil what the 15W50 is used for

https://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_15W-50.aspx

The link I posted was someone wanting to use V-Twin, with Zinc (see thread title, and your previous posts) commensurate with the Penrite oils...Mobil state tht it's all AOK (but they ARE oil companies, who will say anything to sell their product, as you pointed out)

Mobil use 1600+ppm in the V-Twin, and they had no reservtions using it in a car engine...or a V-Twin, which has much the same metallurgy as a car engine, plus more scope for water/high temps.
