I heard that if you have used Mobil 1 you cannot change to another oil unless you completely flush the engine dry. Something to do with the additives in Mobil 1 that can react with other oils.

Never liked Mobil 1. I'd be quite happy to run Valvoline, Comma motorsport (sold as halfords also) or anything with a decent rating on the label.
Why not buy ELF oil from renault?

You get what you pay for at the end of the day! Mobil 1 is the best oil you can buy. Mobil oil is used in formula 1 engines. If you want maximum protection Mobil 1 is the stuff.

seen results of independent testing that say otherwise. Mobil comes out decidedly average.
silkolene pro s 5w40 is the best oil i can recommend and it is esther based, a true synthetic not like all the others. Id rather cut my balls off with a rusty knife than use any halfrauds oil synthetic or not! http://www.theoilman.co.uk/index.php?act=viewProd&productId=7
sure its pricey but you get what you pay for

your choice. I run Comma oil in my 200sx with 300+bhp. not one single issue
"Navy" N17 TWO
Maybe not the exact oil lol but they do use Elf
ITB'd MK1
fairly obvious as Renault own ELF lol
R5 GTT
I have used mobil 1 15w / 50 in my R5 GTT for the last 3 years with no probs if I change oil grade and use 0w / 50 she is a little tappy.
I thought this enlightening and thought provoking article would be of interest. :approve:
A word of caution – You get what you pay for!
Below is an article written by John Rowland, Silkolene/Fuchs Chief R & D Chemist for 40 years.
Quote:
Costs of "synthetics" vary considerably. The most expensive are the “Ester” types originally only used in jet engines. These cost 6 to 10 times more than high quality mineral oils.
The cheapest "synthetics" are not really "synthetic" at all, from a chemists point of view. These are in fact specially refined light viscosity mineral oils known as “hydrocracked”. These have some advantages over equivalent mineral oils, particularly in lower viscosity such as 5w-30 or other oils with a low “W” rating such as 5w-50 etc and they cost about 1.5 times more than good quality mineral fractions.
We use several different grades of this base oil, where appropriate. This is the “synthetic” which is always used in cheap oils that are labelled “synthetic”. Yes it’s a cruel world, you get what you pay for!
Now, you may ask, why are these special mineral oils called “synthetic”?
Well, it was all sorted in a legal battle that took place in the USA about ten years ago. Sound reasons (including evidence from a Nobel Prize winning chemist) were disregarded and the final ruling was that certain mineral bases that had undergone extra chemical treatments could be called “synthetic”.
Needless to say, the marketing executives wet their knickers with pure delight! They realised that this meant, and still does, that the critical buzz-word “synthetic” could be printed on a can of cheap oil provided that the contents included a few percent of “hydrocracked” mineral oil, at a cost of quite literally a few pence.
So, the chemistry of “synthetics” is complex and so is the politics!
The economics are very simple. If you like the look of a smart well-marketed can with “synthetic” printed on it, fair enough, it will not cost you a lot; and now you know why this is the case.
But, if you drive a high performance car, and you intend to keep it for several years, and maybe do the odd “track day”, then you need a genuine Ester/PAO (Poly Alpha Olefin) .
This oil costs more money to buy, because it costs us a lot of money to make, very simply, you always get what you pay for!
