It gets -15 to -25 without the wind chill every winter. Coldest I’ve ever seen it was -41 but that was a couple years ago.
Typical lows are below zero with single digit highs this time of year. 10-30 would likely be fine…5-30 is about perfect
No 20k is far enough for me. It’s an easy number to remember and i have a good saftey margin left in case I can’t change the oil due to injury or I’m in vacation etc.
From what I can tell this oil could likely go 25000 miles though
They could have just as easily mentioned the effects of squirrels getting into the oil pan.
The vehicle doesn't have a coolant leak...isnt known for coolant leaks, and nothing was mentioned regarding coolant leaks in my submission. Pointless on their part.
Bottom line...oil held up...engine...
This is the most recent UOA of my 2019 Tacoma with a 2.7. Vehicle is lifted and running 33 inch load range E tires. This run saw temps in the 80s down to roughly -20F. Plenty of idling to warm up in the mornings and a fair amount of spirited off road use. Truck runs high RPMS...32-3500 RPM on...
Is that based on any science or physical evidence or is it purely an emotional decision?
My plan is to base my OCI on the condition of the oil as determined by a lab. We shall see what they say...perhaps 20k is too long for that lube. If that's the case ill go back to M1 0w40 at a 10k OCI...
Its got just over 100k on it now. 35-40k a year is about right. It had been getting m1 0w40fs at a 10k OCI since the day i purchased it new but my walmart stoped stocking it...much to my chagrin
I put a qt in at around 15,000 miles. It still shows full.
As to checking the TBN...ive run 0w40 at 10k since new and the TBN was always in the 3-4 range with no makeup oil. Im willing to bet im not betting 2 engines on it LOL
Ok guys…hit 20,750 miles on the 2.7 w/ 5w30
I’m going to change it out tonight and refill w/ the same.
Truck only used a qt of oil in the run. Not bad!
