Oil: what do you use?

[Mints]

Just curious to see what oil you NA guys are running in your 1.8l. Doing my first oil change on the car and looking to see what oil to go with. Car also has 131k miles.

I went with Shell Rotella T-6 Synthetic 5W-40. I will probably switch over to Mobil 1, but the Shell is well regarded in Miata circles due to the detergents. If you have lifter noise, this can definitely help resolve it.

I have Shell Rotella in the diesel truck and I run Mobile 1 in both the Spec Miata & MSM.

5w-30??

[Dmn2258]

i run shell rotella 10w-30

[—RuckkehrMiata—]

Mobil 1 High Mileage (10w30), but my motor is very, very old and it is very hot here in Orlando.

10w30 or even better 5w30.Mobil 1 0w30 will work better as well.

Rotella is 5W40 which is good a good choice. I'm currently running some high zinc Amsoil 15W50 in the track car, pretty expensive but probably a bit better protection than a thinner weight oil.

Super Tech oil from walmart is also a good deal.

I use Rotella 15w-40!

I've run Mobil 1 5w-30 full synthetic for a few years now with good results.

Mobile 1 15W50 on the old 305K mile engine.
Mobile 1 5W30 on the new 50K mile engine.

Mobil 1 Fully Synthetic 0W-30

[ya boy willz]

Mobil 1 Full Synthetic 10W30. I'll use Penzoil full synthetic as well if autozone has a good special on it (meaning no Fram filters).

Mobil 1 Fully Synthetic 0W-30.
