Trex101 Posted November 8, 2006 Share Posted November 8, 2006 What would be the best oil for cold weather? Like up to -40° C. A 0wXX zero rate engine oil like Mobil 1 0w40, Castrol Syntec 0w30 or anything that start with zero in front of the SAE engine oil viscosity.

AfterTaste Posted November 8, 2006 Share Posted November 8, 2006 And how come my oil temp nevers goes above 70? Link to comment https://www.sau.com.au/forums/topic/22458-the-goods-on-oils/page/20/#findComment-2651087 Share on other sites More sharing options...
Trex101 Posted November 8, 2006 Share Posted November 8, 2006 And how come my oil temp nevers goes above 70? You mean after warmup and >20min driving, you got oil temp of 70'c? A normal engine after warmup need about 80-90'c oil temp to effectively burn off combustion by product/water that get's in the oil. Anyway where did you live where temp drop to -40'c?

Busky2k Posted November 9, 2006 Share Posted November 9, 2006 ^^ Try your local Mobil distributor. Retailers like petrol stations have their own markup.

Rolls Posted November 10, 2006 Share Posted November 10, 2006 Ive got a HR31 with the older redtop motor, its got apparantly 100,000 on it but its probably more like 150, anyway it blows no smoke and has even compression all over the board so it's in good condition. Pretty much stock standard but it does get quite hot in summer (sits on half temp - should get a proper guage though) Anyway I was thinking something fully synth 10-40 or should I go something thicker like 50w for summer?

Busky2k Posted November 10, 2006 Share Posted November 10, 2006 Nah stay with the 10W40. If it doesnt use any oil it doesnt warrant a thicker one! Link to comment https://www.sau.com.au/forums/topic/22458-the-goods-on-oils/page/20/#findComment-2658979 Share on other sites More sharing options...

Oh well, I guess I'll have to fork out the money, unless there is something better than Delvac for 70 bucks?

khunjeng Posted November 12, 2006 Share Posted November 12, 2006 hey trex and busky2k I'm getting confused with the diff oil...read stuff about it and thought i was cool... Castrol Syntrans and Syntrax..75W90 I think they are spec'd at. I have a stock s1 r33. I used Syntrax as it was GL5 rated oil...wondering if I should have used the Syntrans..I get confused with them..Its not for LSDs and I have no idea if I have one or not lol I guess I should know.

Busky2k Posted November 12, 2006 Share Posted November 12, 2006 Castrol Syntrax 75W90 - GL4/5 suitable for both diffs and gearboxes. Castrol Syntrans 75W85 - GL4 for gearboxes only but tends to give better shifting than Syntrax for gearboxes specifying GL4 fluids such as our nissans. So you chose the right thing!

Just in the Castrol spec sheet it says not for LSDs...but the stock R33 diff is a viscious LSD and aparently this is still cool...but I'm still not sure about that.

Busky2k Posted November 12, 2006 Share Posted November 12, 2006 When an oil is spec'd for LSD use, they mean its appropriately friction modified for clutch LSDs. Most of our LSDs are viscous coupling (VLSD) which means they use their own internal fluid for the 'lockup'. So for VLSDs it doesn't matter if the oil is specifically rated for LSD use or not - just so long as its API GL5 rated. So you are safe with Syntrax.

Nismo_God Posted November 17, 2006 Share Posted November 17, 2006 Can someone please confirm if 20/60 is too thick for my r33? When i give it a bit the oil pressure rises to nearly 8. should i drop the oil and put in some thinner oil?

If all else being equal, oil pressure is inversely proportionate to flow rate, the higher the pressure the lower the flow. You are starving your engine of precious oil during startup and before oil temp is up to operation temp.
