#4503064 - 08/31/17 08:04 AM M1 0W40 in a Civic?

Recently got rid of the mercedes and now have at least 5 gallons of M1 0W40 laying around.

Was wondering, can I use them in any of my Civics, calling for 5W20 or 0W20?

If so, does anyone know a link for any OCI analysis report? Thanks for all the input and help.

P.S: Would it cause any harm or no issues?

I would go ahead and use it. I have it in all my cars and trucks, including the Ranger which specs 5w-20.

If VVT no, VTEC yes. VVT & VTEC NO.

Sounds too tic toe ...

Most hydraulic VVT needs a viscosity sweet spot not far from OE spec oil grade.

You can use it straight. No problem. It basically a 30 weight oil anyhow.

If you want to mix it with a M1 20 weight go ahead. I'd mix in M1 5w20 HM....

No problems at all. I'd use it in the warmer months and 0W-20 in the cold...

Possibly a slight hit on fuel economy due to high HT/HS viscosity, but otherwise no harm, IMO.

You can technically mix M1 0w-40 and the 20/30 grades but they have completely different add packages. The M1 0w-40 has very high calcium (2800-3000 ppm)/no magnesium. The lower grades are very low calcium (1160 ppm) (about 40% of 0w-40) and strong magnesium (700 ppm). If anything, I'd be more comfortable mixing the M1 0w-40 with other high calcium/no mg oils like PP, QSUD, and Castrol Edge 20/30 grades. Though in the end, your engine just might not care.

You'll never be able to tell a difference in those Honda engines. I have three and they get whatever is in the stash at the time. I've never ran a XX-40 in them but if that's what I had, I wouldn't hesitate.

These engines in other parts of the world spec 0w30 or 0w40 with those systems, I guess those systems don't work properly and yes its the same engine. I wish people would stop spinning this absolute falsehood, these engines were not designed to run on xw20 they were designed to run on a wide range of viscosities and can run on xw20 for fuel economy reasons, there is no "sweet spot" in fact many Honda xw20 engines with these systems eg J35 ivtec/VCM show remarkably good UOA's on 0w40.

OP run the 0w40 and forget it, its fine.
