price of the Royal Purple kinda rules it out for a change every 5oook for me..

I did some oil sampling a while ago with my schooling...penrite did extremelly well.

that good penrite is only 5 bucks difference.

if it lasts longer then it would be worth its money.

im disappointed about Elf as i can get it extremely cheap.



but im usuing Valvolines new stuff and if thats good the stuff i got shld be better

I saw this in the magazine it came out of a couple of years ago
Is a pretty disapointing test really as it doesnt have Castrol Magnatec, they claim all sorts of wonderful stuff and it's the oil I use... has kept my GSR motor goin for 290 000 km

penrite is a better quality oil that most because they are independantly owned they don't have to buy all their base materials from the same place, which means they can choose a better quality base material, and therefore manufacture a better quality and protecting oil

From what i was told by reputable people..dont know if it holds 100% truth,but penrite were/are buying their base mineral extracts from pensylvania in the states..apparently the oil there has the highest naturally ocuring EP constituents in it from the ground..higher than anywhere else known ..This EP (extreme Pressure) property is naturally occuring therefore wont breakdown..its the additives that break down and render your engine oil lifeless after time goes by...if its natural it cant be degraded at anywhere near the rate of an additive.

I would like to see a test on oils done after being subject to excessive heat,carbon and fuel contamination,and a set amount of shearing and film deformation..Because in the true world,this is what happens,and the longer it can perform in these environments..the better the oil truly is.

By the looks of it those tests mostly dealt with EP..which is a good indicator..but there are factors like detergents,dispersants and anti foaming properties as well as resistance to sulphur build up from petrol deposits at certain temperatures which can attack bearings.. which all add to making an oil a good choice,especially over a peroid of years..

My 2 cents

i wouldn't go by those results anyday.. from the looks of the machine and how it works, high viscosity oils would be far more effective in that situation..

also anyone read the redline part? it says their oils reduce turbo lag.. 8)
