5w40 motor oil

I've been using LM 5W-30 Special Tec for about 2 years now. Interesting how LM's website ONLY lists the 0W-20 but FCP actually recommends the 5W-30.

So they are saying to use 5-30 vs the 0-20?

I have been using a great 5-30 for some time now. When I changed over to it the engine became quieter and ran smoother. I noticed this immediately. I personally would not go back to 0-20.

This is what I changed to some time back:

Schaeffer Manufacturing Co. 8008-012 Advanced European Performance Mid SAPS 5W-30 Engine Oil

Toyota says 0w20 (0W-20 LL14FE+ Rated oils.) because they most likely have to for CAFE standards. But FCP says dont use LL14FE+ as its garbage because CAFE standards suck and will harm the engines long term and that we should only LL01 Oils for the B58.

My climate can range -20 to 100F, and the 0w20 is good for -31F to 86F. A little low for our summers. So i want the 5w30/40. 30 being good up to -22 to 96F, 40 is good up to -13F to 104F. I also dont get cold enough to ever need 0w as I wont really be driving my supra under 20F, I have a daily for that.

So 5w40 is my best bet because of my climate but unfortunately LL Special Tec doesnt exist in 5w40, so 5w30 it is. Im for sure going 5w30 with LL01 protection and good HTHS (High temperature/high shear viscosity) and will work just fine for me.

I do like Schaeffer as a brand as well. Ran that plenty in my MKIV.

Turner MS had a special that was in stock, Liqui Moly 5-30 (or 40). Bought that this last time and tracking the snot out of her. My fav mechanic now has Motul 8100 X-Cess 5W-40. So I‘ll use that the next time.

I can’t remember which oil thread but a chemical engineering page had a member on there that I liked and recommended that (for track in a hotter climate). Works for me
