Valvoline Super Diesel 15-40w engine oil

Steve,

I also used to use the Valvoline SuperDiesel in 20 litre drums.

But for the past couple of years, changed to F_U_C_H_S Ultralube 15W40 CI-4 for about $70+ for 20litres from Adelaide Truck and 4wdSpares (DonKyatt shop).

Its a higher grade, and cheaper.

Cheers
Phil

Hi Steve,
Have you ever tried the Penrite range of oils?
They have oils for all types of applications and it is made in Australia for Australian conditions by an Australian company.

Cheers

I used penrite twice, once in my lsd rear on my gu patrol rebuilt that found the oil was thinning too much on long trips well after about 1hr on the hwy. Second time in my gearbox same vehicle, rebuilding that now. Lack of oil to the main bearing same thing happened the oil thinned but ever when cold it had the consistancey as water and the colour of engine oil after oil 6 months and about 10000ks. My front diff, transfer case and engine in which i use castrol are all fine funny that. I would try castrol RX super i use it my father uses it in his v8 diesel gmc and his mate uses it in all his 86 semi's cant go past that i reckon.
