Engine oil Shell or Eneos

First impressions - engine is noticeably quieter and smoother at idle. Engine temps is lower by 1 line. slightly better throttle response. As for fuel consumption, i have to drive more my usual route to know if there is an improvement.

Rotella T6 0W40.

Phattbotti tuning has done oil sample tests in multiple oils and he says Rotella T6 5w-40 is the best bang for the buck.

I use Castrol for the Nexon and Punch. The Safari uses Shell. Shell and Castrol are by far the best I've come across. Shell is much much better for the cold weather, by what I've observed.

I'd stick with oem or put some better stuff like Motul or Eneos into it. Eneos has some relation to Honda oem oil I forget the story. I use to put only mutul into my car but have recently switched to Eneos, will be putting eneos 0w-20 race prior to tune.

My 96 xj I would put in 5 quarts of rotella 15-40 and a quart of Lucas oil stabilizer purred like a kitten

Our Blueprint crate 383 stroker calls for Rotella as an acceptable oil for daily use. Cheaper, too.

Run Rotella in my 80’s and 90’s BMW’s often. They seem to like it, and sometimes it’s cheap at Walmart.

Ran t4 10w30 in my 95 Cherokee for the whole time I had it and it loved in. Never ran better

mobil 1 is trash. i go with castrol5w40 or motul 5w40 or rotella diesel 5w40
