Engine oil Shell or OEM Mazda

Same tayo ng Unit OP (Aerox V2)

Natry ko na both yan and mas nagtagal ako sa shell longride. Sa opinion ko lang mas smooth sa Makina yung shell long ride yung ultra scooter smooth din naman pero nagstay ako sa longride kasi ayun ang recommended viscosity sa Manual ng Aerox V2 (10W-40).

Shell ultra 15w-50, been using that in my reborn for 3 yrs now, buttery smooth.

Tried Shell Advance Ultra once no complaints, felt a bit quieter overall But I went back to Motul because the bike just felt more responsive with it.

I like motul for my Merc. But I just swapped in shell rotella 5w-40. Had some tick on startup and now the car feels smoother and quieter overall. I have a 92 with 73k

Shell high mileage oil.

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines](http://www.cleanmpg.com/community/index.php?threads/45295/#post-357910).

Rotella T6 15W-40. I’ve used it in all my bikes, cars, lawnmower. It’s the best option if you own lots of motors. Just change it frequently.

I've been running Rotella t6 and a wix oil filter for years on my 04, 3k miles everytime, and it's currently still running with 245k miles.

Mazda’s OEM 5w30 is a little too thin for my blood considering the engine temps when driving hard, fine if you’re going to never redline the car

When I tried it on my MT-07, though, I found a lot of false-neutrals that my bike didn't have before. I drained it out and put Motul back in after about 300 miles.
