Which Oil?

[Guest boosthrd]

Just wondering which oil is good for the RB25T,would Mobil 1 be the go or Penrite 10 Tenths or do you think mineral oil over synthetic

I use Motul Engine oil and Redline Gearbox Oil, do a search for either of these and you will have hours of reading.

I am doing an engine oil & filter change today.......

I wil get Mobil, probably 5W-50 or 10W-40

I have Mobil 1 something in my car right now... won't be using it again (if I can help it) as it tended to 'go off' rather quickly.

The Castrol GTX in there before was all right for ages.

What do you mean "go off"?

Look at the colour. Does it look the same coming out as it did going in? It should be right but it does not inspire confidence...

if you're feeling rich go for royal purple. about $80 a pop last time i checked

mobil 1 does seem to go off.. i have checked my oil a few times since last service and it's been sweet, only a light brown colour and didn't look like it had used any... then i checked the other day and it's below the low mark :uhh: and also turned quite dark. only just 8000km since last service on a pulsar, so even on an NA car I'd be changing it at 5000km intervals in future or be very careful about checking your oil regularly

I have read somewhere that if the oil turns dark colour it is actually good as the oil does what its supposed to do-carry combustion byproducts away from the cylinders,among other things,hence the dark colour.

$80!!

I will give two thumbs up for Royal Purple - but $80?!

I swear I paid less than that last time.....

It is excellent stuff though boosthrd.

i run motul 300v 15w-50 in my r32gtr and we run 6100 10w-40 in our shop 180sx - used to run mobil 1 but found eng oil pressure reduced over time - motul maintains its viscosity longer - importantly change the oil often i do it every 5000k and also change the filter remember oil is the engines life blood
