[holdenvx38]

hey all,
just fine tuning some bits and peices on the car, jsut wondering about Royal Purples syn oil, apparaently it is alot betetr than your avaerage fully syn oil. Iv currently got Penrite Sin 5 and its a pretty decent oil but iv seen a lot of good stats/reivews in magazines about Royal Purples stuff. There should be and artical in street commos next issue where they dyno using all royal puprles products but has anyone used the stuff b4???????? known anyone who has????? how did they go????????????
hey rekon u can get like 4-5% power gains and and like 2% torque gains. its like $85
any ideas????????????????????

Its good stuff, the threads are littered with info on it. My criticism of it is its price for something thats not even a fully synth. Take note, the stuff used in the magazine and what most people use which is available at Autobarn and Eagle Autos is not the top notch stuff and not the same as the stuff the magazine is using, the racing grade is what you are after and needs to be ordered. Normal stuff has the grade across the bottle, the racing stuff has a number reference which equates to different grades. That is the fully synth stuff. The normal stuff which is still very expensive is a blend.

Hmmm... so false advertising then? All those stats about royal purple 'out lasting' other brands and being fully synthetic is crap if what you buy in retail stores isn't whats being tested. If this is true then I'm not impressed.

....boutique oils. They only exist because they can convince some of the gullible public that their motor is going to fall apart using normal oils and if they really care for their car to put in their brand etc.......

Royal purple came 7th in a recent test just slightly ahead of the castrol edge oil

What was the test for, done by whom, How many oils in total and what oils beat royal purple? Details man, details!

For the record, I've never used RP.

I wouldn't be suprised, which test is this ? Who were the top 3 ? I am very disappointed to see that BP who have bought out castrol are ditching their own oils, fantastic stuff like Visco 5000 and Corse Plus. What they sell now they restock with Castrol which is a shame.

Like i said the full synth stuff is called Racing **

Royal Purple Sythetic Oil

Thats the stuff you really want and tested. You will notice its in the racing section, not the Automotive section.

Some botique oils such as ULX 110 and Brad Penn are actually pretty good, one being full mineral and the other having synthetic and semi synths. They are tried and tested and scrutinized. Amsoil is good stuff as well but does not suit all cars.

[vxcalais_01]

Im in the process of trying to choose the best diff oil, and even in that the Royal purple did very very poorly, yes Amsoil won it and was probably somewhat endorsed by them(test), but they only came second in some test, even Valvoline beat RP in some things.

VX look for something EP rated- extreme pressure that is.

Thansk Brad, Penrite Sin Gear 75W 90 Seems a good one at $40 for 2.5 litres. RP, Amsoil, or Castrol SAF-XA are possibly full synths but dearer.
