New M1 EP SN 5w20 Outstanding

[chubbs1]

I have waited about 1k to post this but I have been running this oil in my '10 Civic (see sig) and have noticed an incredible reduction in engine noise and vibration, even performance. I am now a firm believer in "the right oil for your vehicle".
Just previous was PU 5w20, M1EP 5w20(SM), Amsoil 5w20 XL 7500.

I highly recommend the new M1EP 5w20 even if you are dismayed by the formula change (as I was), definitely did not expect this.

Denso 150-1010 oil filter is in service now as well. Previous was a K&N HP-1010. No other changes made.

All three (PU 5w20, M1EP 5w20(SM), Amsoil 5w20 XL 7500) are all upper-tier oils.

In your situation, all it means is that your isolated engine has a liking / preference for the Mobil SN stuff. I have found many GM 3.4's like Pennzoil Platinum 5w30 and many of the now older Ford Police Cruisers / Taxi-Cabs like Motorcraft 5W-20. My other Chevy (S-10 4.3) runs smooth-as-silk on Maxlife 5w30.

So isolated engines do prefer one brand and one particular oil weight over others.

The right oil for my rigs is the oil that's on sale. I've never noticed any reduction in noise/vibration with diff oils, let alone an "incredible" reduction. Glad it's working for you

I'm in the same boat as hate2work. I use whatever big brand synthetic is the best deal and have not noticed any difference between the lot. I noticed a difference in my car between 10w30 and 5w30 when I had to use up this bottle of M1 10w30 that was sitting in the garage; so I have some ability to judge small differences.

It is good to hear that it is working for you.

M1 0w20 was noticeably noisy in my '06 Mazda 6. Really! I would describe it as a cheap hollow clangy sound (best I can do). All other oils I've tried in this vehicle have been normal quiet. Otherwise I'm an M1 fan, but not 0w20 in this vehicle.

Nice report Chubbs! Some people will say oil can't quiet down an engine. In my experience in certain instances this isn't true. When I switched to the SM version of 0W20 Edge it was much quieter in my Liberty, than PP 5W20, M1 0W20 and ASM 0w20. IMO quiet is better than noisy. It is actually easier to detect noise if you park in a garage. JMO

EP has always been outstanding.

Have you noticed a mpg drop? I put in the Mobil 1 EP SN formula about 2,000 miles ago, and immediately saw a 1 mpg drop that has not returned. I'll be dumping this on the next OCI for regular Mobil 1 SN or Amsoil which did not drop my mpg.

I started using M1 0-20 in my Duratechs last year and it is very quite in both engines. My mileage has also picked up about MPG. WIN! WIN! for me.

Have you considered the change of the fuel formula for the summer blend? They do oxygenate the fuel for summer emissions. That will lower MPG a tad.

Typically mpg increases in the summer months, its the winter fuel that sucks [more]. That plus the fact that the computer can lean the fuel mix faster when it's warmer should increase mpg a bit. JMO

Very true, but here in the mid west they change the fuel formula also for summer months. That's one reason why gas prices are often higher here in the late spring verses other parts of the country. The formula change creates a slight shortage so prices go up. Usually about now production catches up with demand and prices stablize.

Just changed to 5W20 EP SM (remember the AA clearance sale?

) and 1/2 qt of M1 0W20 just because I had some laying waiting for work. So far so good.

I didn't know that Tig. I would think that the warmer temps and getting the engine running leaner faster would play into it as well. The truth is when it comes to gas, gas prices, or anything related to gas the little guys can't ever win! JMO

I'd be more inclined to lean toward the filter change possibly causing the reduction in noise. I'd also believe that if an oil of the same visc causes a small four cyl to vibrate, or to not vibrate, its within a few minutes of catastrophic failure on the "vibrating" oil.

Indy, it is not a horrible vibration warranting mechanical check, the engines on those cars are just "not particularly smooth".

 

[chubbs1]

Have not logged any increase or decrease in mileage. Just a much better drive. The filter could contribute as well, I will have to experiment
