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.

Go read the 200 pages of the dedicated oils thread here on sau.

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.

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.

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 :P .

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.

      I can believe it if you're getting air into the pickup. Cavitation is tremendously destructive for pumps.

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info
