GTR - Which Oil & Oil Filter?

[meshmesh]

Guys I was wondering what motor oil some of you use in your GTR's and perhaps what you could recommend for a GTR that doesn't see any track work.

I normally use the Mobile Super Synthetic, but remembered some of you use the Motul stuff... which of the Motul oils should I use considering I don't do any track work?

Oh.. and is there any difference in oild filters? or just the standard RYCO stuff? I can't find the thread, but someone was using some brand other than RYCO and said it seemed much better.

Im using Motul 300v, expensive but very good oil.

I have been using this since I got my R 18 months ago

[Amaru]

I have used Mobil 1 5W-50 ever since the engine was built (10,000kms ago), seems to be ok but the lifters are noisier than most of gtr's ive heard so might change soon.

I used to usually use a Valvoline oil filter, but got a Ryco this time and it seems to hold oil pressure a bit better (with the Valvoline filter it would drop pretty low on idle).

i am using Motul since i can get it at staff price . Also Mobil, shell, castro and some orther brand are local made but motul is different.

Castrol Synthetic Formula R, 10w - 60w & Ryco filter

Normally just strain the old oil through a stocking and reuse it.

When it gets too thick to go through the funnel, I replace it with Big W Super - $10 for 4 litres.

Too hard and messy to get to the oil filter on a GTR, so don't replace it.

Thats some funny shit.

ihave used redline 10-40 synthetic... expensive thou...great product.

[DAN00H]

Redline in my engine, gearbox and diff with ryco filter - expensive, but so far it has worked very well - very smooth.

MOTUL 300V 15W-50, good enough for Nismo, good enough for me:)

Pureone filter

Don't NISMO use there own oil, I think it was a 15w-40 from memory.

MOTUL 300V 15W-50, good enough for Nismo, good enough for me:)

Isn't a rating of "15W" to thick for morning starts?

[Ronin 09]

MOTUL 300V 15W-50, good enough for Nismo, good enough for me:)

Same here

PS anyone ever smelt it? Smells good... maybe I'm just weird...

[Steve]

AFAIK, its what Nismo use.

meshmesh, if it has a W rating, it has been tested to flow at 0degC. The W means its suitable for use in winter. The winter viscosity is tested differently than the weight. It is a little thicker than say Mobil 1, which is like water. The winter testing involves seeing how much oil will flow throught a specific sized hole at 0 deg. Basically how well the oil pours.

The weight of the oil (50 in this case) is tested at 100deg celcius. The higher the number the thicker the oil at that temp.

Ronin 09, I know what you mean, sort of a honey smell:)

[meshmesh]

Thanks Steve, what did you pay for the Motul?

Snappy google search turned up this

from this website: http://www.motorspot.com/300v.html

this is also backed up on the Motul Canada website.

and from http://www.motul.com/300V/motul_300v.html

it was given high praise by the subaru world rally team cheif engineer, plus others.

[Steve]

I think it was around $75/4litres at autobarn.

[meshmesh]

I think I might try the Motul this time..

Just got off the phone with Motul, and although they suggested either:

300V 15W-50 or the 300V Chrono 10W-40..

They recommended the 10-40.. bugger only comes in 2litre bottles. How many litres do you need for a GTR RB26?
