just wondering whats the best brand and best performance oil i could use in my datsun 1200 ute. just has a the origanal diff and gearbox??

Not sure, but I use redline bit, pricey though.

meh i dont mind the price as long as its gonna make it last longer im turboing my datto so just thinking of changing the oil wouldnt surprise me if its still they same as when it came off the factory line lol!

I used castrol syntrax 75w90 on the weekend in both diff and gearbox, nice and smooth shifts very pleased with it, was going to use the redline stuff but couldn't get the super light weight at the price I wanted so went the cheaper option, still $75 for the 3 litres I needed. I used 200ml of autotrans fluid in with the oil in the geaerbox.

I used redline in my work van for easier gear shifting (as quoted by redline) but made no difference :(

I use Nulon oils in my cars and customers cars and havent had a complaint yet. They have quite a range to suit different applications in full or semi synthetic and basic mineral oil. Been using it for a few years now and really impressed with it. Also easy to get, (supercheap auto, bullseye, bursons etc) and reasonably priced.

Always used about a 50/50 mix of synthetic mobil 1 gear oil and synthetic atf. Worked well for me.

just tax it from work if you're a mechanic like me

im using THUBAN GEAR OIL EP 80W 90 (caltex) used in box and diff bout $20 bucks 4lts....really anything above 90 your just wasting your moneys....unless your going to use the car for drag

For the diff, Mobil 1 Synthetic Gear Lube 75W-90.

But the gearbox needs GL4 specification.
