Oil change questions

[Chops]

In my first Miata, an '02, I used nothing but Mobil1 full synth 5w-30 and standard filter. In the '02 Blazer I had and in my '10 Nissan Cube, I run Amsoil signature 0w-20 along with an Amsoil filter. In my BRG, it came with Amsoil Signature 0w-20 and Amsoil filter. 24k miles later, I swapped that out for Pennzoil full synth 10w-30 with a Bosch x3 oversize filter so I can go another 20k+ miles.

Mobil is overrated. I used to use Mobil, then switched to Castrol. Now that I have my own shop and a deal with Eneos, I use them. Usually 5w-30.

Eneos is by far the best I've used. I knew the second I started pouring it. It literally EMPTIED the bottle within a minute. Usually oil continues to drip from the bottle for a few minutes. Not with Eneos.

What ever weight or filter you choose, changing the oil on a NA miata is extremely simple. Is a 20min job for me and I just started changing my oil when I got my na in March 2010. I say NA because I know on my msm its a pain because I have to remove my passenger side tire. Just follow the tut on miata.net and you will be fine.

With all that said I run either Pennzoil or valvoline pure synthetic 5w30 and purolator pure one filter.

Why 0w40?

Why not 0w40? Its probably the best mobil 1 made right now. With 5w-30 EP in a close second.

0w40 i believe is far better i work at and oil shop by far the strongest oil we carry and the cars that come back with them stops burning oil aka anything made by VW tends to burn everything and 0w40 does the trick to fix the problem

easier startup than 5w and thicker when at operating temp, nice especially with a turbo making all that heat.

interesting. Thanks. I'll try it out next change.

Why? Does it taste worse than other blends?

OP still hasn't reappeared in this thread, I hope you figured it out!

I'm on the Rotella T6/German Castrol boat. It's usually Rotella for the Suby and Castrol for the Miata.

And forget about the crush washer thing, I never replace it and my oil pan has never leaked from the drain plug.

I dont have a washer or seal on my drain plug.

Just pure dino-oil, Castrol 5w30, change every 500ish miles.

[Maikeru]

change every 500ish miles.

Why so early?

[SKAR]

Because boost, heat, 2k into the bottom end and low cost for oil changes.

[xjdesertfox]

run a stouter oil made for boost, have it last longer, send out a UOA ...... profit?

If I was boosted thatd be one of the last oils on my list.

Why don't you send out your oil to get analyzed after 500 miles? It's super cheap and I guarantee you that you could be running your oil for much longer than that without issues.
