What kind of oil do you use ?

[84Prerunner]

Tundra and 4 runner get Oreilly brand full synthetic, both have over 350k miles.

the ol "racetruck" gets Rotella T4 or delo 400.

Everything I own gets its own oil lol...
My newest Duramax, Rotella Full Synthetic 5W-40 (thing gets like 4-5k miles a year so I change it yearly anyway)
My daily driver/work truck LLY Duramax, Rotella Syn Blend 15W-40. Stuff is loaded with active additive, so far the TBN on the oil samples has looked great at 9k mile service intervals.
Anything old with a flat tappet cam I run Valvoline VR1 10W30
the two newer gassers either get Valvoline or Mobile 1 full synthetic 5W-30

I’ve been trying HP Lubricants 15w40, I like it

Always run Baldwin filters

How much zinc is ok with cats? I’ve been wanting to use Cenpeco diesel oil as it’s cheaper and I always had great luck with it in diesel trucks

Meet Chris 6-7 years ago and have only run Maxima since. For me it’s a great partnership

Motorcraft Syn. Blend 5w20 or 5w30 in the prerunner and daily (both are 2.3L Duratec's)
Mobil 1 5w-30 Syn. high milage in the 4.0 OHV Explorer

Motorcraft filters in everything, I can usually get everything at Wal-Mart the cheapest.
