I'm about to do the syn swap on my 4WD and add a Fumoto but this time I'm also going with Kirkland brand full syn and again a WIX 51348XP filter.
FWIW, I use Penta air filters |
How long have you ran your Fumoto valve for now? I’ve been nervous about running one, but decided it would be worth a try. I also ran PUP for about 30K+ miles and Blackstone sent me a good report. TBN was at like 2.2 on the sample and it had 4,468 miles on it when I sent it in.
I was pleased to read good things about the Kirkland Signature full syn oil. Do you ever run oversized oil filters? I’ve also never heard of Penta air filters before. I’ve had great results with OEM so far so I’ll stick with them/Denso.
