Penrite Oil HPR 30 20W-60 (Mineral)

Used penrite hpr30 for years in my 1990s corolla. A few months ago I bought a bottle of the new formula oil. Noticed the bottle was different with a different lid and also a new foil deal under the cap. When I broke the seal I noticed that the oil didn't have the usual smell.

revving as freely. Checked the dipstick and noticed that the oil was very sticky which seemed odd. Found out later from shop I bought it from that penrite hpr30 has a new formula for high mileage engines. Seems to me like it's just full of cheap butt stop-smoke now.

cheaper mineral oil I just change it alot more frequently to keep it fresh. I will continue to use this product as it provides great engine protection.

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.  Show details ·  1

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.  Show details ·  1
