Hey guys, Been around the forum for a bit but this is the first post and thought it would be interesting to all (as they always are). This is for my brothers 2017 Forester XT that ran Napa 5w-30 Synthetic for almost 6K miles. About 80% highway and 20% city, but lives at high altitude here in Colorado (about 9k feet) and this was the oil run through most of winter up here as well, so motor experienced many early morning cold starts near 0 F and below. Car has somewhere between 45k to 50k miles on it and he's been the only owner. Honestly, I was surprised how relatively little fuel dilution there was for the run with no make up oil needed and viscosity held up well overall. Flash point was a little bit lower than average but not too concerning really. All in all, report came back pretty good and happy with the way the oil performed. I've used Napa Syn Blend several times for both my Outback 3.6 and their syn for the Crosstrek's in the finally with no issues and good results each time. Anyway, Napa was drained and replaced with Castrol Edge 5w-30 and old filter was a Puralotor boss (will try and do a cut and post when I can get my hands on a filter cutter) and replaced with a Napa Gold. Enjoy!
