Hi guys. I have a 1989 First Generation Trooper with a 4ZE1, 2.6 engine . It hit 251,000 miles. I’ve been using Mobil 1 10w40 high mileage oil. 4 years ago I installed an OEM IHI Turbo and manifold from a 1989 Impulse. Running 13 psi. Should I keep using this oil? I want this engine to last another 250, 000 miles. It is not my daily driven vehicle. I only use it in my farm and some 4x4 trail trips with my friends once a month.
I was planning to upgrade to 15w40 Rotella Synthetic one.
By the way, I live in a Tropical island where year’s average temperature is 80 throughout the year. I live in the mountains. On winter it can reach 60F and on summer can reach 100F.
I was thinking about 20w50 but I think it is to thick.
Based on the vast experience of you guys, what would be be the best oil to minimize shear and wear ?
Thanks in advance for any advice.
