Penrite 10w-50 vs 10 tenths?

Hi all,

Received a bottle of Penrite HPR 10W-50.  Reading posts and The Goods On Oils it seems the consensus is Penrite 10W-40 10 Tenths.  It is for an R33 GTR.

For the uneducated (me), I'd say the HPR 10W-50 is fine.  Before dumping the unknown oil in there, what are people's thoughts on the HPR 10W-50?

Cheers!

Motul all the way for me but every car is different. Since you have the oil (one bottle? - what's that in litres>) just chuck it in and try it - your motor won't seize up  - just monitor heat, oil pressure etc and see how you go.

Cheers. It's a 5ltr bottle.

Lol.

It's all dependant on the age of the motor and the intended purpose.

Use 10w50. It'll be fine.

Want more info?

It's about 330 pages. I had a look, TLDR it all... It's a forum; I used search, looked at the stickies and asked a question. That's what happens, right? Maybe I'm simpler than you, sorry.

It's only an RB26 just use anything 40 or 50 weight and it will be fine.

I run 10tenths 10w40 in my forged RB25. Been a good oil so far.

HRP10 is a 10W-40 oil that has some additives that makes it a '50' when hot.

Racing 10 (10Tenths) is a full syn oil (more expensive, on par with Royal Purple, Motul Chrono, etc, group 5 oil I believe?)

Either will be fine. The Racing 10 has better shear properties at high temps/pressures. So if your engine cops some track work, I'd use that over HPR. HPR is fine for street driving.

Thanks @niZmO_Man.  That's an actual answer!

The huge oil thread has the answer, but it can take quite a while to trawl through it. You'll learn heaps though, people like to get technical around here (which is a good thing). Now go read the RB oil control thread .

Oh and on my GT-R, standard engine/boost/no oil cooler, I ran Racing 10 (10W-40) and Premium 5 (5W-60) on the track with no noticeable difference (going off engine noise and standard oil pressure gauge, car ran hot because I didn't flush the cooling system). Back in the early days I ran HPR10 for street duties and it was fine.

My answer was an actual answer. But I have used 15W-50 in my car for years and it has been fine. 40+ degree drift days at QR and I beat my engine harder than an unwanted red headed stepchild and it has never let me down. No oil cooler either.
