What a perfect day to change oil in the jeep. It was running M1 HM 10w40 on a 7500 mile oci and today it is 48*F. Couldn't have asked for a better day to change the oil on the jeep, considering the hard winter is yet to come.
The jeep just hit 149.1k miles and should be just now getting its legs loose. After a two good oil changes where cold start lifter tick (hot or cold temps doesn't matter) wasn't present with M1 HM 5w30 and 10w30, it came back in the 10w40. It was at it's worse in 40-50*F weather. This morning it was 40*F and did not make a peep, hoping it continues to be quiet.
Last oil change:
6 qts M1 HM 10w40
TG8A
This oil change:
6 qts M1 HM 10w30
TG8A
With the winter I think I'll go for a 6k mile oci. The 10w40 experiment was nice but I think I'll just stick with the 10w30 regimen.
Although all my TG8A's have looked good, I will have to look through my BITOG archive because I think this one was by far the best.
