Can you be a bit more specific? Their site has quite a lot of 10w40 grade oils: http://www.motul.com/nz/en/products?f%5Brange%5D=25&f%5Bviscosity%5D=28&page=1

I haven\'t watched the full eight minutes but there\'s no hot testing involved with that demonstration is there?

High Heat, High Shear properties are a major consideration with oils. As they all behave differently as they get up to working temp (or overheated).

I dont buy into that vid at all. Without naming names you have no idea at all what spec/product hes really comparing to the sponsored product. Oils are built to a spec. If it meets that spec it meets that spec period. Some may be better but technically it should be pretty bloody similar to stay within spec. Some oils claim to be backwards compatible like caltex have their CI which was upgraded to CJ at the same $ and they claim its fine. A lot of cases it is most oil companies are working towards this. Really theres so much more to oil than oh this is so much better than that. I want to see actual evidence for just one engine failure that was a direct result of shit oil that was correctly specced. Most engine oil is fine in petrol/diesel just the diesel related have a higher detergent level along with other modifiers. Funny thing is the majority of oil comes through Singapore for our markets anyway through the same plant just to the individual oil companies spec.

Oil n00b

Higher of either is \'thicker\'; first number is cold, second is hot (simplistically)

The second is more relevant though as that\'s what it\'ll spend most of its time at.

Worth noting that cold starts is where a lot of wear occurs so thats also just as relevant.

My libero had a forged engine and I ran it on forementioned agip semi 10W40. Being 18 at the time I quite literally thrashed the pants off it. Dropped from redline numerous times each weekend night. Once the roof went on it I thrashed it cold with ice on the windscreen but just couldnt kill it in 40thou of ownership.

Yes. oops :-[ Motul 300V Chrono 10W/40 For my upper Hp stuff.

As for the Royal Purple vid? Against Motul?....I dont reckon there would be a lot of difference. Spec for spec of course

[tebbyj]

I thought i better post this again for anyone who missed it.

Does make for good reading. Is the same test as in the Royal Purple video but with a more varied range of oils. Its a bit out dated still gives good information on brands.

Penrite 5W-40 for me (changed from Castrol even though I work for a Castrol agent) was going to run Motul 300V but even at trade price I couldn\'t really justify it even though I\'m sure it\'s a good oil. Serviced every 5,000km V8 WRX STI.

Well thats very interesting Well worth a read. May reconsider my choice of oil. Its all about expectations versus application. Cost? No such thing as cheap. or free.
