I have been using hpr15 for the last 2 years but the last 2 months it has started burning oil!!! Not sure if the oil is too thin or there is something wrong but i will start using a thicker oil.

Should i switch to hpr30 or hpr 40?? Sorry for hijack.

little thin cold if its got hi kays on it, hpr 30 better choice all round.

Its got 270,000km at the moment i think its the valve guides not the bottom end. What would be the disadvantage of using HPR40 or even their 50?

the 40/70 hpr 50 will build oil pressure to slow, your kays are high enough to use hpr 30

Also run it! On a recon engine with only 15000 now been great. It does tend to get dirty quick thats all shows it cleans well!
