Hi BITOG Members,
First post on BITOG, but I'm a long time/occasional lurker over the past 15+ yrs. I see there was a recent post for a '19 Golf R with some recommendations, but that car sounds like it is stock and the factory fill oil is a different, lighter weight on the newer gen Golf R's vs the older mk7 Golf R's like mine (2016). Factory fill on the 2016's is 5w-30 or 5w40. My car has roughly 37k miles. Been running Castrol 0w-40 since I purchased the car in April 2019 @ 29.5k miles. My R is a 2nd car which is reason behind the lower annual (4k/yr miles) mileage. Previous older (60yr+) owner was 2nd owner and took impeccable care of the car. He purchased with 7k miles on the clock. He used Motul 5w-40 exclusively (not sure which version Motul) and was religious w/ changes at 4-5k intervals.
Although the 4-5k annual miles the car sees now is low, a good portion of those miles are hard canyon carving/spirited driving and if weren't for COVID this past year it would have seen track miles as well. The car will be definitely be seeing some lapping days this year at High Plains here in Denver area.
I tuned the car almost immediately when I purchased it and it has progressed from there. It has been on ethanol blends for fuel for the past 1.5 yrs. First on the stock turbo for a year @ E40 and now on a larger turbo @ E30-E35. I just dyno'd the car and it's @ 499whp SAE Corrected (415whp uncorrected...here in Colorado so we take power hit with the altitude). Anyway you look at it power is quite a bit over stock.
So with all this said, I know Castrol 0w-40 is held in high regard here on the forum for the most part. For my non-track/street miles is there a preferred oil vs Castrol 0w-40 to use seeing a good % of the 4k-5k annual street miles are also hard charging miles?
For track/lapping day I plan to run Motul Sport 5w-40, but have to see how my oil temps look during sessions. May run something even heavier, at least initially, since I don't have an oil cooler....yet. Some people have had good success running something like Liquimoly 10-60 for track days only on these cars. The data seems to point to a ~15 degree drop on track day oil temps in summer moving from 40w to the 60w. Our altitude definitely exacerbates cooling issues, so I do have concerns on that front.
My other concern are the ethanol blends I run on this car. Does ethanol have a negative impact on the oil over time that would necessitate more frequent oil changes?
Thanks in advance for any input/recommendations you all can provide!
