‘93 Mustang, 2.3L 4-cyl, 5 speed manual, believed to be 133k miles
Out: Unknown, Fram Ultra
In: Harvest King 10W-30 conventional, Purolator L30001 (white can)
If you want to believe the date written on the filter, the oil was last changed in 2011.
2001 Toyota Celica GT - 130k on vehicle
Out: Castrol Syntec Blend 5w-30 (old SM rated), Fram Ultra XG4967
In: 2 qts old Castrol Edge, 2 qts old Castrol Edge Syntec and .5 qts Castrol Syntec Blend, Fram Tough Guard TG4386 (trying oversized filter). Using up a bunch of old API SM oil I've had sitting around. The Syntec blend is over 10 years old and the old gold Castrol Edge was the first stuff brought to the U.S.
About 10 months/5k on last OCI.
2018 Toyota Tacoma TRD off-road 4x4
19500 miles 5k miles on Mobil 1 FS 0w40
Dealer change to bulk 0w20. Last free oil change.
Noticed a purely qualitative differences in how the truck runs in the 375 mile run to work on Wednesday. Could have been the wind or new washer fluid. Or that they added to much air to the tires, I have released some.
Up in the air on how long I want to run this. Leaning at 2-5 then back to the FS M1 to round out the 10 k on the filter.

First since buying it used
2018 RAM 1500 SLT 5.7 QUADCAB 16,150 mi
OCI unknown, olm was at 67% figured why not just dump it after 1000 mi of driving after purchase
5k on oil (I realized it was going to be July/August and 100+ outside and worse in the garage when I needed to make my normal change at 7500. So I cheated.)
Out: Valvoline Advanced synthetic 5w-30
Fram Ultra xg3600
In: Mobil1 5w-30
Fram Ultra xg3600
I've been jumping around between oils the last few changes - I'll be going back to Mobil1 for the foreseeable future.
