Thanks for pointing that out. I'm still putting together all the puzzle pieces, doing my best to make sense of it all.

So 0w-20 oil is the recommendation by Toyota. I see that definitely being good Fall thru Winter. So possibly a 0w-30 ( or 5w-30) in Spring thru Summer ?

The two kickers of having a oil cooler for your engine: 1. initially watching for leaks, take care of them asap. 2. upon doing an oil change , making sure all the old oil is out of the system thru gravity . If the engine takes about 7.5 quarts of oil, not sure how much extra ( 1-2 quarts ? ) the oil cooler will hold upon doing a oil change. Its extra oil for the system, just making sure to drain it all is important.

On the oil cooler situation, can anyone recommend a good system to go with ? I'm not up on brands and models, of what's what.

Thanks in advance
