How much does turbo light , royal purple and SIN cost? i my self use mobile one and have done for years. im planing on trying motul because i hear its a bit cheaper.

Actually Steph you would need a thicker oil for an old motor, you may find it blows some with a thin oil.

Most of these oils run around the 55/75 dollars for 5 litres. Money well spent.

I like the penrite SIN product, its been in my GTR since it was rebuilt and no hicups so far.

holds good oil pressure and keeps inside the engine nice and clean. but the engine is only 20 000ks old so its still eairly days.

Last time I bought my oil it was $89.99 at autobarn slacks creek I am hoping there is somewhere cheaper than that as I do think they have raised the price from $79.99 (5L) Anyone know where to get a better deal on Royal Purple?

also whats your views on oil filters I have been using the KnN ones so far are the cheaper brands as good? what about genuine?

I run Shell Helix Ultra, about $50 for 5L - SR Automotive recommend it as Stu runs it in his ARC and Drift cars

Another vote for Royal Purple.

I have dyno readouts from a study conducted by Fast Fours or Hot Fours (can't recall off hand) showing Royal Purple topping the list for power with Mobile 1 coming second.

They used a almost stock Honda Integra and they tried the various oils in it 1 by 1 and dyno'd it with the various oils in.

Everyone has an opinion on what oil is good and for the most part nobody has any scientifically proven reason why. For this reason alone I chose to try Mobil 1 and Royal Purple and I must say that I could swear I felt the difference if thats possible.

Cheers,

Ben.

i have attached the results of an oil comparison taken from zoom magazine. i don't have the article as i have issue 109. they have printed this table at the start saying one of their previous issues (105) ran that article but the table wasn't formatted correctly

as you can see...

most power came from: nissan genuine, mobil 1, castrol magnatec, fuchs titan

least power came from: pennzoil platinum, valvoline xld

does anyone have a copy of issue 105 for more info on their testing?

Good stuff with the scan. I will try to find my mag and scan it up.

Shame Royal Purple wasn't listed on that comparison, would have been nice to see the results.

Is the dyno power read out a good comparison as to how the oil protects?

no, but how can one possible determine long term protection in a clinical manner?

different engines, different condition, different drivers

it would be impossible to do a double-blinded randomised control trial comparing oil types.. that's the gold standard for clinical evidence

Try "Hi Octane" for a cheaper buy price on royal purple. They've been advertising a lower price than autobarn.

I got my last 5litres for $75 and that sheet (power and oil pressure) seems true on the road- I noticed a difference over Motul with more power and oil pressure and temp stability out of the royal purple

PS. REDLINE on the list is the same Royal Purple 10/40 I believe

Awesome Ivan is the man!

Are you referring to Ivan Lee at Hi-Power Racing or is there an Ivan at Hi Octane as well?
