I may be the only one here doing it. I am running 0w and 5w30 I'm the winter. I may run 0w-20 cbut it would only be in the summer. 30wt on winter to counter fuel dilution.

Interesting, I wonder if it helps for valve deposits too.

My dad had an great deal on Castrol Edge 5w30 only, 23$ for a 5L jug, its a very very good price. I want to stock up on it but I'm worried about warranty.

If you're still under warranty only use what the manual says you can use.

Get Pennzoil Platinum 5w30 at nearest Walmart, it's supposed to be on sale at C$27.77 for 5L jug, then apply for MIR online with Pennzoil, it's $10 off a 5L jug which should make out to about $20 for 5L after taxes and after rebate. Max is $40 rebate per person/address at this time. Watch for further rebates later too.
PP in 5w30 is border line xw-20 oil while giving room for fuel dilution and has a healthy dose of cleaning agents.

That's odd, I typed my previous post once and it posted twice. I edited the spelling, and it posted again.

True, but it's cold enough to cause fuel dilution, especially with short trips.

Is there evidence of sever fuel dilution in these engines? Doubt it.
 
I run 0w20 in my 2019 2.0 skyactiv miata but I plan to switch to Mobil 1 Extended Performance 5w30 here in socal for the summer. I'll take the extra hot visc at 7500 RPM. If i do get any sort of dilution, there is enough of a buffer. Same exact engine in Europe recommends 0w20 OR 5w30. Not sure how Mazda would void your warranty when they state 5w30 in mexico and rest of world. What if my brother in Tijuana changed my oil.

Sorry Tig1, but yes. I sent off a sample of Mobil 1 0w30 with 4500 miles ,vehicle miles were 7300.

I noticed the dipstick level rise a bit. It's what prompted me to run this uoa back in Nov 2018.
This was after my wife's typical short trip home from work.

Knocked Mobil 1 0w30 which is a stout oil, into the 8.0 cst range.

None of this makes sense.
 
What part does not make sense? I'd rather take the slightly higher viscosity in the case of fuel dilution or during my high rev canyon driving. It's a 6MT, I'm not driving around at 1500 rpm in 5th gear. I think there would be less blow by in my situation as well. The car is spec'd either grade in europe, same engine.
