I used mobile 1 5w50 and it seems to burn on the track.
using motul at the moment, but was gonna give the nulon a go
No i will not say its better, i'm just saying nulon is fine.
Anyways, Mobil 1 is the best fully synthetic oil because it is the only true Group IV oil thats readily available on Australian shelves. The next true fully synthetic oil is Amsoil which is harder to get here.
Nulon, castrol, shell, etc... claim to be fully synthetic but they are actually highly refined Group III oils. Castrol won the fight to call there oil fully synthetic through some loop hole.
So yea, alil lecture, but Mobil 1 top shelf stuff... comes with the price tag too.
i've read from somewhere that says that Group IV oil needs some mineral oil in it to carry all those addictive and cleansing agent. its all in the blend ie. it could be 90% group IV + 10% group III. or 10% Group IV + 90% Group III which is hard to find out.
as long as the oils meets those european standard like VW 500 505 MB229.51 BMW Porsche etc etc. its good enough oil for my honda, as long as the viscosity is suitable.
today after a very tedious search for royal purple, i decided to settle for Valvoline Full syntenic, what the other posts say about the grades its best to use thinner oil if u you engine is fairly new. Best to use thicker grade oil's for older cars wit 1xx xxx mileage. I would also recommend a popular oil like Valvoline as 99% of the mechanics have the oil readily available so it saves time and if your stuck in the woop woop you know u can get your hands on some. Btw not good to mix oils, pick one and stick to it till you sell the car.
Also best to look up the owners manual whats the recommended grade and buy either that or better. (every mechanic should have this book)
