It has been suggest that it is more important is to change the oil regularly than the brand of oil.

Wear is something you would have to judge, personally I change oil regularly.. it's cheap insurance as I say.

Sure sure sure. I am not saying RP is not a good oil. As for it increasing power that is not unreasonable either. I was just questioning your statement that RP saved your engine.
Sorry,I am pedantic and my friends get amused and annoyed with me in equal measure.

Real questions seems to be - whats the best fuel for the 86?

Captain Snooze · 08-16-2012, 08:02 AM

Fuel? I thought we discussing engine oil.

Loki556 · 08-16-2012, 09:35 PM

Yep, but apparently using wrong kind of fuel on this car causes pinging.

SXE10 · 08-20-2012, 06:04 PM

Use 98 & you shouldn't have a problem. (although after reading this post maybe not http://www.ft86club.com/forums/showthread.php?t=13827 )

Back on topic, I'd stick with 0w-20 or 5w-30 to avoid any warranty issues. If you want extra protection use Amsoil, Redline or Motul. http://www.ft86club.com/forums/showt...213#post392213

Ive used the HKS 0-25w oil and my car likes it, I have seen very little in the way of Oil usage and im upto 8000km already 2nd oil change just finished and used about 0.25 litre in that time

MSTiFK8R · 11-06-2012, 01:09 AM

warmed to 90C , OW20 shows only 0,9-1,0 bar pressure idling

kinda scares me, I 've never used such waterish oils

but still, if it's prescribed in the service manual, should be fine

Oil with a low viscosity reduces frictional losses. However, oil is also responsible to seal the combustion chamber properly:
The oil film between the piston ring and the cylinder wall can tear off if the oil film has a low viscosity. This reduces the combustion pressure and with it power.
Racing engines usually run thus on an oil with a high viscosity. http://pitstopusa.com/i-8583247-motu...ase-of-12.html

In short: Using an engine oil with a low viscosity may actually result in less power despite the fact that the frictional losses are reduced.

We are going to run the Royal Purple XPR 5w 30 at Bathurst (Easter). We have the HKS oil cooler... Once we are done we will have the oil tested..
Practice, Qualifying, 2 x 30 minute sprints and a 1 hour enduro... it will be interesting to see the change in pressures and temps from the genuine oil it has at present.. still only have 530k's on the clock.

We will take some heavier weight in case the conditions get very warm.. I suspect not though given the weather in NSW lately.

SXE10 · 03-17-2013, 05:13 PM

Have you thought about using Motul 300V 5w30? It doesn't get much better than that off the self. Be worth while getting a UOA done on the RP to see how its holding up

rx3 put some 20w60 in your BRZ & let us know how you get on

Your whole statement is incorrect. Most race engines will run a thinner oil in qualifying to gain more HP. Do some reading on HT/HS. BITOG is a great place to learn from http://www.bobistheoilguy.com/motor-oil-101/

You forgot to mention the proviso: 300v is a race oil and is not designed for extended use. It is great if you plan on changing your oil every 2000 kms or so.
