Keeping the rotor happy.
Was hunting around for ages for a decent mineral oil, synthetic ones cause some issues with rotary engines (Google it).
Used the engine recommendation tool on their website, and contacted them directly to confirm my research and landed on the HPR 30.
Engine is loving it and I don't think she'll be seeing any other oil from now on.
Seems To Be Good Oil!
Purchased a old hilux with high kms, was running shell helix 15-40 and mechanic done roadworthy put castrol 15-40 in it, seem to run alright but was burning threw it. had rear main seal fixed and then swapped to HPR30
and so far the old ute runs better. i do have small timing chain rattle but that's due to old owner not doing regular maintenance.
Great oil for my old cars
I have been using HPR30 in my Model A Ford for a lot of years, four years ago I purchased a 351w Mach1 Mustang HPR30 is perfect for this as well, stays nice and clean in both engines. The HPR30 oil is perfect for these old engines that require the high Zinc content.
