Fair enough... but perhaps also consider adding in a bottle of Biotech Lubegard with the PUP as well ;)

Your HEMI will thank you!
Yes i do add a bottle of this stuff every oil change. @Burla got me using this stuff a couple years ago and everytime i head to the usa i pick a few bottles up.

Same!
I just like it to circulate a little bit before heading out.

Too many times I have witnessed those who literally, and especially in dead of winter temps, fire it up stone cold and have it in gear before the starter has disengaged.

I FN cringe when I see and hear it.... their vehicles are crying like a pup who's dad has just walked out the door without them!
Oh man that is the worst, you can almost hear the wear happening

@Burla is a pusher... lol

All kidding aside... the Brain-Trust Herein have been invaluable to us noob's in determining what the best approach is to ensuring the longevity of our engines.

Without all these great contributors to our knowledgebase we'd be lost AF, myself included!!

Kudos to all the amazing participants of RF who make this the most incredible platform it truly is! We owe you all a great debt!

Mobil 1 0w8 has arrived...
some guy did some uoa's and the wear came down with 0w08, but it was a brand new engine,. lol. Like duh. But apparently they are putting this in toyotas, which scares me. They blew past 0w16 straight to 0w8 and they have toyota oem 0w8. I will have to see if rav 4's will have a low visc cel, if they do I may have to give up my favorite choice for our next suv.

They put out cars with 0w8 spec before api even allowed 0w8 for USA use, lol??

Dude says additive package was responsible for lower wear despite low visc, but fails to say what additives that is. We know it cant be zddp right? So what additive would make 0w8 wear like 5w30? Your guess is as good as mine. Fake sulfur type additive?
