That's a dedicated racing oil, you are probably, since you DD it, better using the VSI:

Ester based oil molecules also carry the added benefit of having an electrical charge. One side of the molecule has a positive charge, while the other has a negative charge. This means that ester based oil molecules are always going to build up a layer of protection between metal parts during cold starts. The 8100 X-cess, 8100 E-tech and 300V oils are the highest performance lubricants available today. In fact, Motul led the way in 1972 with the first ester based oil for vehicle use, and still leads with the introduction of Double Ester technology (Esters, polyolesters, and other complex esters combined) in 2004.

Further info re application to modified VW's:

8100 X-cess 5w40, SDS... says:
LUBRICATING OILS (PETROLEUM), C20-50, HYDROTREATED NEUTRAL OIL-BASED
DISTILLATES (PETROLEUM), HYDROTREATED HEAVY PARAFFINIC

That doesn't scream PAO to me.

the ravenol VSI 5-40 looks good 3.75 HTHS + a noack of 8

Is the 8100 x-max the same ?

Typically you want to beware of running of a "racing" oil in a street application because the oil is not intended for a street vehicle application; emissions equipment, extended OCI's, etc. But Ravenol Racing oils are different in that they actually carry formal OE approvals, so you can rest assure that you can run the oil not only on the track, but also on your street driven vehicle in normal applications. With polualphaolefin (PAO) based oils with a special additive content of tungsten and a trinuclear molybdenum, the oil specs are some of the best motor oils available anywhere.

If you look at the spec sheets for the products in question, RCS carries zero OEM approvals:

Whilst VSI, which I already linked to, is formally approved by numerous OEM's.

Their 5W-30 REP carries the Dexos 2 cert, why I "chance" (

) using it in the summer in this VERY hot running (still on the factory radiator) 1.6 EcoBoost.
