Anyone using 0w20 Mobil-1 oil in Metro/Swift?

[wmjinman]

I was going to be really clever and change to Mobil-1 synthetic oil in 0w20 weight in my '99 Suzuki Swift 1.3 liter 4 cylinder for the ultimate low resistance deal. Engine is said to have about 7000 miles on it and is VERY "clean".

But my mechanic just about had a cow - is all worried it might ruin my engine, etc. MetroMPG said he's using it in his, and I told my mechanic, but he said something like, "Well yeah - in Canada - it's COLD. He can get away with it there."

So I guess my real question(s) are; 1) How hot does it get there, MetroMPG, and do you run the 0w20 all year round? And you said Mobil-1, right?

and 2) Does anyone living in a warmer climate use this stuff successfully?

On the one hand, I'm a bit annoyed at my mechanic for not just putting the stuff in like I wanted him to, but on the other hand, if he happens to be right, I'd sure hate to damage (or prematurely wear) my beautiful "new" 7000 mile engine for just another 1/2 mpg, or whatever.

Anyone? Thanx

bump to top.

Anyone using 0w20 in ANYHING? I'm hoping to tell my mechanic in the morning it's working fine for others.

Maybe its worth running 5w-30 for a while and reseach the matter more until your next oil change. If you're having second toughts about running 0w-20, i would probably just run on stock oil and change it next time. Walking around with fear of doing something that potentially can hurt your like new engine isn't fun.

My 2 cents worth of thinking... Sorry for not contributing to the initial question though.

Geez, you bumped this thread 3 times while I was asleep! Run the oil the manufacturer recommends.

The 0W part is not going to matter because that is the weight of the oil when it's at 0C/32F the 20 weight part of the oil weight is the weight of the oil when it's at 100C and the question there is if the oil is thick enough for there to be correct oil pressure or is your oil thin enough that it flows to fast out of the bearings and you loose oil pressure, 2nd part of the problem is if the oil is thick enough that it is held back by the seals or if it's thin enough that it blows past seals and rings and you burn oil.

0W30 is thin when cold and the stock weight when warm and is listed as a legit replacement for 10W30 motor oil.
If your mechanic doesn't want to put that in, then change the oil your self.

Make your own blend if you're nervous. Mix some half-n-half 0w25

EDIT: "hot" here is maybe 30-34 degrees C for 2-3 weeks in midsummer.

One more thought:

Put in whatever oil you want, then get an oil analysis done after x miles. That'll tell you exactly what's going on.

You like testing stuff - this is right up your alley.

They recommend at least 30w hot.

I posted this on your other thread, but I'll put it here too.

The 0w oils are Mobil 1 fuel economy oil and the 5w-30 is normal Mobil 1.

0w-20 @ 100°C = 8.7 cSt
0w-30 @ 100°C = 10.9 cSt
5w-30 @ 100°C = 11.0 cSt

0w-20 @ 40°C = 44.8 cSt
0w-30 @ 40°C = 62.9 cSt
5w-30 @ 40°C = 61.7 cSt

Sorry for my ignorance, but what is the cSt?
Thanks
