Hi

There are a couple of situations where the Pro R is the better option than the Pro S. As the viscosity gap is smaller in the 15w-50 than 10w-50, the oil is more stable as less additives are needed. In reality, that doesn't matter unless the car is getting a fair amount of track use as 10w-50s are pretty stable anyway. The other time the Pro R is the preferred choice is in forged builds with loose tolerances. The thicker cold viscosity can prevent the oil getting past the rings before the engine warms up properly. Same applies with piston slap.

In general, unless a car is either mainly/totally a track car or has larger tolerances, the 10w-50 is the best choice, but there are less 10w-50s to pick from. If you want to use Motul, Gulf or Redline, they don't make a 10w-50, so you're limited to a 15w-50.

Cheers

Tim

Oilman I'm going to be ordering oil from yourself tonight but what is better the 10w50 Titan pro S or the 15w50 Titan pro R? My car is getting mapped to around 450hp,Ida mainly for the road,also any ideas why my oil won't heat up proper,goes to around 80 in town then way back down to 55ish driving at 60mph, it is kinda cold just now but this oil temp is very worrying

I'm no expert, but your oil thermostat may be stuck open.

Any I'm about to embak on my first oil change of my GTR. It's running around 700bhp and has forged internals. You can hear that it is forged when cold. I may get a few track days next year.

Would 15w50 be best?

As per previous poster sounds like thermostat isn't working - or it's simply not a thermostatic set-up....

The oil isn't getting hot as there is too much cooling and at that sort of temp you want to be going for a 5w-40 or even 5w-30 rather than a 50. The airflow passing over the cooler at 60mph is what's making the temp drop.

Cheers

Tim

Ok but is 5w40 ok for a fully forged engine as I've read 15w50 for forged

The oil viscosity needed comes down to oil temp and the amount consumed. Your oil is not getting hot enough to need a 10w-50, you'd only really need to go for a 10w-50 or 15w-50 if the oil consumption is really high. Burning some oil is to be expected with a forged build though, so don't go for a 10w-50 just because it's burned something like half a litre in a thousand miles.

Cheers

Tim

Hi Everyone,
"Oilman" Would you be able to guide me in the right direction please.

R32 GTR , Australia. I've got a oil cooler which keeps my temps around 60-90ish depending on the day... Took it to a track event and didnt see over 90 degrees due to the cold day... but im currently running 10-40 full syn royal purple but now i work for a place that distrobutes Fuchs oil, and i was thinking about running a 5w-40 SuperSyn Fuchs , Fully syn...

I was just about worried about it being to thin for the car being a older car Its got 70000kms on dash but i never believe that...but its defs not something super old because its still punching hard on the dyno for a near standard car. Just exhaust / elec boost controller tuned.

I want to reach 320 kw on HKS GT-SS's too in future

Your help is really appreciated

Btw Best thread ever read

With that sort of power, I'd go for the Fuchs Pro S rather than Supersyn if you can get it, but 5w-40 is correct at those temps (in fact, you would ideally want the oil to get a bit warmer).

Cheers

Tim

Yeah Thanks for that, Yeah i was worried about it being to low? is it dangerous to be so low :S?

maybe i should make up a bash plate or something so the oil cooler doesnt work as well.

the Fuchs Pro S is what grade and thats full syn?

would the race oil be ok for 99% street use though?

5w-40 is absolutely fine, it's not too thin, at 90C it's pretty much spot on, I'd actually consider a 5w-30 unless you get the oil temp up. Some of the additives in the oil only activate around 70-80C, so really you want to warm it up a bit.

The Pro S comes in 5w-30, 5w-40, 10w-50 and 10w-60 and it's fine for road and track use.

Cheers

Tim

wow ay thanks for your help man!
might make a bash plate so it doesnt get such a direct feed of cold air.

thanks for your help once again. so detailed

Glad to help. The Supersyn should be fine. If you can get the GT1 5w-40, that's between the Supersyn and Pro S.

Cheers

Tim

Hi there, I am rebuilding my Evo's engine installing forged pistons and con rods. I live in sub-continent so the average temps are between 30C to 40C.
Which oil grade and brand will you guys suggest for running in ? and after running for daily driving/ odd drag races?
