So the main crank bearings on my toyota wore out prematurely. No one knows why but i got a new motor put in it. I looked up the bearing clearances and they are the same as when the engine was originally designed 12 year ago: the 5w30 era. Looks like they've made some changes to the head and increased the compression. Ive only used tgmo 0w20. It's cheap and everyone praises it.i was changing the oil earlier than needed too since i get toyota parts discounted and i wanted to take care of my truck. Anyways, i will switch to 5w30 soon, most likely amsoil.
When i think about it, the truck has had good weight added to it, and it's running over sized tires on a little 4 cylinder engine. It's a manual so the engine is essentially always under load as it's either making power or it's engine braking. Also admittedly the engine does get revved out occasionally. So I'm concluding that this engine is being run under either severe or very severe duty lol. Im thinking moving up to a 5w30 oil will be beneficial and will prevent the premature wear that i saw on the first motor at 20k miles.
I just wanted to consult with the knowledgeable guys on here as im basing my decision off of bits and pieces ive read on here.
