Oil to use

#1 Post by Ltriumph » Thu Mar 08, 2018 7:20 pm

I have a discussion going on with a mechanic that does some work on my car. I purchased Penrite HPR 30 20W - 60, he said I should have purchased a 20W - 50, is the Penrite wrong for the car?

I suppose 20-50 was the original spec oil but I cannot see a problem with the oil you have purchased, I don't recall 20-60 being available anyway when our cars were current models, I imagine you just have an oil that at a higher temperature will still retain the correct viscosity compared to the 20-50, of course both oils will perform the same at low temperatures.
Hope this helps,

I've used {use} 20/60 in my 2500.Seems to hold better oil pressure when hot.

Hopefully not needing too many bits.

Hopefully don't need bits !

Oh dear. I replied to the other instance of this question! Not that I said anything different to what's already been said here.
