Penrite HPR 15 diesel oil...

it seems to be popular that Penrite HPR 15 is a popular choice of oil for Landcruiser owners.

This has a different viscosity of 15w-50 compared to manufacturers recommendation of 15w-40.

Why would people differ from recommended oil?

Are there benefits of this and what are they?

I have read the Penrite website they mention it's 'above manufacturer recommendations'. Or is this just salesmen doing their stuff again?

Any thoughts greatly appreciated.

I prefer Penrite oil over any other oil,(engine,diff,gearbox,etc) but have recently changed to Castrol Super RX for the Prado and its as good as any i reckon. Have never tried any other oil in it but, i wanted something that was 15w-40 (Manual recommends 5w-30, which is really only fully synthetic and too thin for the Kimberley temperature) to cope with the temperature and conditions up here.

When chosing oil look for its API rating (i think) and see what car manafacturer recommends, match these two together and get as close to possible with viscosity and ya laughing. Believe me every Toyota dealer uses a different oil so dont think that it matters too much. Look for the letters CI, CJ, CD etc, the lower the letter in the alphabet, (CJ for example) the better the oil. The 2nd letter represents standards for a certain year for which that oil has to exceed. To do with emissions, soot, ability to self clean, etc all in all to make the newer high tec cars run perfectly. I think the latest is CJ but not absolutely positive.

Have used Penrite for 15 years in all my vechiles, petrol and diesel and will not use anything else.
I used to work in an engine reconditioners for 8 years and if you had seen the difference that oil can make then you would understand.
ie carbon build up, wear, cleanliness in the engine ect.
Penrite was by far the better oil and if you follow there recommendations then you go wrong.
They cannot afford to recommend the wrong oil because it could cost them heaps.
This is just my view.
Each to his own, bit like toyota verses nissan!

Hi. You don't state what model Landcruiser you want the oil for but HPR 15 is normally recommended for a PETROL engine. For the 80 series Penrite recommend HPR Diesel 15 and for the 100 series Diesel 5. I have used Penrite Oils in a workshop for over 10 years and can Guarantee that they perform ABOVE manufacturers specifications. Just stick to what Penrite advise for your model vehicle and if you require more information contact their help line.

Have to also endorse Penrite - our mechanic of the last 30+ years has always recommended it. The best two examples we had were successive Peugeots, a 505 and a 405 diesel, traded with 350k and 370k kms respectively, still running in good condition.
Currently running a WRX with 184k km, still feels like new, and a Hilux D4D with 90k km ditto.
The oil is good, but having not used anything else cannot say what other oils are like. I recall the 505 was starting to use a little between changes, but the 405 never did, even at 370k.

Regards. John.

I have read on that penrite is one of the few oils that has a high calcium content and as such is compliant with the jap cruiser requirements. Japanese CD is a different benchmark to SAE CD. Jap CD requires lots of calcium. On the early turbo diesel cruisers, no bigend issues with Japanese models, but heaps over here. MMmm
