So my foray into alternate oils for my VW Golf Sportwagen is over. Prior to this year I was using Liquimoly products and additives exclusively in this car – Leichtlauf High Tech 5W40 and Molygen 5W40 which has the tungsten-based friction modifier. I decided to give a few other popular Euro oils a try that you can get at Walmart or Costco that many here on BITOG recommend/like. Firstly was the ever-popular M1 FS 0W40; I picked up a 6-qt case at Costco for $35 (normal price - they do have it on sale once in a while). Next I tried the QSUD 5W40 from Walmart for $18/5qts (normal price), and finally the new M1 FSx2 5W40 for $24/5qts (rebate didn’t work on this variant for whatever reason). I used Mann filters for each. Did ~4-5K OCIs for each. VOAs and UOAs for both have been posted in their respective forums and should be easy to search/find. My data look fine all the way around with these products as one would expect. My car is modified/tuned and gets driven hard. Typical oil temps are 210-220 but will get up to around 240 with some hooning in the mountains. I see no consumption worth noting with any of the oils I’ve used in it since new. Here are my data:
The slighy climb in Fe after the new larger turbo was installed about a year ago...who knows. Will be interesting to watch that trend and see if ~10ppm is the new norm up from ~5 before installing it. Finally, it seems to be that all of these oils on average drop the same/similar amount w/r to viscosity over an interval - I've stopped caring..hahaha
In the end, I like Liquimoly products and have gone back to using them - have Molygen in the car now. I get my LM oil change kits from FCP Euro so after the first kits these are free (less return shipping) with their 100% lifetime replacement guarantee and since I use Paypal to purchase them, I get refunds for the return shipping so these are truly free after the first one! You could even nerd out and get the last one and sell it making the whole thing a free affair. There is a small hassle of returning the used oil etc. which isn’t that much drama to me and I include my other consumables (wipers, cabin filter, blah blah blah when I return things and have 3 vehicles I do this with so get some economy of scale on returns). I used M1 0W40 for a huge portion of my previous ’00 MK4 Jetta’s 14 year/220K life so was always happy with it…it is an excellent oil and I'd use any of these that I tried without hestitation. If one of the local Walmarts ever finally marks that QSUD down below $18 I may get some for my Atlas! It's a rural store so likely not many Euro oil afficianados in the oil section...they had 12 5qt jugs last I was in. Hope these data are useful to others.
