2013 Golf R - Motul X-Max 0w40 - 4353mi

[mkosem]

I just got back the next sample from my Golf R. This car is set up with an APR Stage III kit with runner flaps deleted and an additional low pressure fuel system upgrade. This setup is supposed to be good for ~450hp at the crank. This one is looking much better than the last couple on Motul Specific. These wear numbers look solid for a young FSI engine, and it managed to shear down only one grade, rather than 2, in only 200 fewer miles. I've got the same stuff in the sump again now and will shoot for closer to 5k miles this interval based on these results.

The oils here are:
Motul X-Max -w40
Motul Specific 505.01
Motul Specific 505.01

Blackstone's comments were:
MATT: This sample does indeed look better. Iron is at the lowest level we've seen so far. Of course, this is the shortest oil run we've seen too, so that explains some of iron's improvement, but the steel parts did leave behind less metal per mile here than last time, so that's definite progress. Fuel at 0.8% is progress as well and this small amount isn't indicative of a fuel system problem. Rather, we're probably just looking at a little fuel from normal use like idling or taking the sample cold. The TBN is 4.6, showing plenty of active additive remaining.

Do you have any links to UOAs similar to your engine, but stock? I wonder if the iron is a lot lower? I know you have an iron block, and the iron shown is directly proportional to the surface area that's being swept by the piston rings.

There's a general purpose 2.0T FSI thread on this forum. It isn't specific to the CRZA variant in this car, and doesn't have any in the same state of tune as mine as far as I can tell, but has many UOAs from engines of the same basic underlying design. It can be found at http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1396680

Try Mobil 1 0w-40. Worked great for my double the horsepower + track time recipe
