Default Running Mobil 1 10W30 in Winter in Canada

Hi,

According to the Mobil 1 site:

10W-30 Above 0 F
You can use Mobil 1 with SuperSynT 10W-30 with confidence. This
viscosity is also available in Mobil Drive Clean OilT and Mobil Drive Clean
PlusT High Mileage formula.


5W-30 All temps
You can use Mobil 1 with SuperSynT 5W-30 with confidence. This
viscosity is also available in Mobil Drive Clean OilT and Mobil Drive Clean
PlusT - both the Newer Vehicle and High Mileage formulas.


I am rather confused by this rating since the pour points of both oils are
identical. I want to run the 10W30 so that the extra oil film would quiet
the piston slap I have on my 2001 Buick Century on cold startup.

Depends on the engine and how you drive and for how long you drive.
I used 20-50W on a 4 banger for years, winter and summer. Put
234,000 on it before trade in. Was still running good, no compression
problems. Tried the same thing on a V8 and it didn't like it at all.
Operating temperature difference. Many recommend the synthetics
for your situation. I'd stick to manufacturer recommendations.

Just my 2 cents:

I usually run 5W30 in the Winter. When I'm too lazy to change the oil
myself, and the schmoe at the service station puts in 10W30, I can tell a
difference on winter-cold starts, and I'm only in NC.

With the 5W30, it seems to turn over a little easier and run smoother
until it starts to warm up the oil (ok, so that takes all of 1-2 minutes).

In the summers, I don't notice as much of a difference, so I just grab
what I can, although I do try and get 5W30 year round. But here, Mobil 1
5W30 availability tends to get spotty during the summer.

Using a thicker oil may not help your piston slap at startup. I would think
that may be caused by something inhibiting oil flow. That is if you are
only hearing that at startup and not at run time. In the winter, most cars
will need either a 5w or 0w oil to help get oil flowing on those cold
mornings. Synthetics are pretty good in cold weather too.

I hav a quart of Mobile 1 Super Syn 5w-30 infront of me. They say it pours
down to
-54F(-48C).
