Honda Bottled 0w20 vs M1 AFE 0W30 - 1.5T

[chris719]

I run M1 FS 0W-40 in my 2010 Mazda 3 specifying xW-20. It runs fine and my UOA are slightly better. I also have not experienced any notable degradation in fuel economy.

There's a bigger difference in terms of HTHS, which is more relevant to the engine than KV. The HTHS of a euro xW-30 is 35% higher than a 0W-20. That's greater than the difference between a 0W-16 and a 5W-30 API oil, so it could be thought of as being over 2 grades thicker than the 0W-20, and more than a grade thicker than an API 5W-30.

These are just a couple of the reasons why I use Euro and some boutiques in all my vehicles. Except one which I’m testing R&P.

Bonus.

Does it really matter given that Honda specs a 10W-30 for use? I think not. If they only spec'ed xW-20 it might matter, but even then, what's going to happen?

Less wear and more tolerance for fuel dilution.

Exactly! The ONLY engine that I have even heard of that had an issue with a higher viscosity oil is some of the GM V8's (I forget which family) that had the cylinder deactivation system that **seems** to be viscosity dependent. I chalk that up to a bad design versus anything else.

Aside from that I have never in all my years heard of an engine that had issues or increased wear with a higher viscosity oil.

Neither.
Got to Canadian Tire and get a jug of Mobil 1 Extended Performance 0W20. It goes on sale regularly for ~ $42 CAD.

If you're changing it at 50% OLM, whatever the cheapest Dexos1 Gen3 oil on sale, 20 or 30 weight. The ATS 2.0T (300hp tune) gets SuperTech 5w30 D1G3 at 5k mile intervals. It's got 100k miles on it now, and runs like a top.

Does it really matter, LOL... Oh, the tropical temps of Ontario....

Hence 0W-xx...

If it's any consolation I run the M1 EP 0W20 on my Type R in Montreal.

21 Sonata N Line. Purchased while I was in Texas working on family matters and now living in Arizona where it is 108° as I type this lol. Been using M1 AFE 0W30 since the first oil change at 1000 miles. Analysis done at around 28,000 mi. Only 4,200 mi on the oil because at that time, Hyundai was giving me my free oil changes, although I brought them the oil even for the freebies because I had no idea what they should be putting in there. So I paid for an oil change at 1,000 and 4,000. Hyundai paid for them at 8, 16, 24, and 32. I paid for the additionals halfway between each because I'm a typically a 5K oil changer. I've been changing it every 5k since. I'll be taking a sample with next month's oil change which would be around 59,500 mi.
