hi guys i came across this youtube video showing a comparison between these synthetics and Royal purple to my surprise came in one of the last in terms of flow in cold temperatures. I was planning on running with royal purple in my suzuki sx4 for the winter up here in Northern Canada. Now i'm second guessing my choice. Would you guys agree there's better oil brands for cold temperature winter use?

Heres the link.

If you are worried about cold start definitely use a 0w instead of 5w. RP is overpriced, I prefer Valvoline or M1 any day

cool video If it get's that cold where you are I'd go with a 0w oil plus you can thin oil by using some mmo or rislone ...

You may also look into an ester based synthetic as they have superior cold pour points in many comparisons.
0W-30 is impressive for cold pour point. Noack is better with the 5W-30 but probably isn't as much of a concern with those cold temperatures. Mobil 1 is great and cheaper than Red Line but doesn't match its cold pour performace per published specifications.

Up there, I'd be all over 0W oils smile

And no, I would not use RP ...

I just put the royal purple about a month ago with a new oil filter. Can i drain the rp and pore in the mobil 1 and leave the oil filter on place without changing it yet? Can the mobil mix with a bit of the rp that was left in the oil filter? Or do i need to do a complete oil change?

Bit upset about buying 5- 5 liter jugs of this royal purple a few weeks back.

All my family in North Dakota get Mobil 1 0W-20 recommended to them by me.

It's fine to leave the filter on. Personally, I wouldn't extend the oil change very far, but there won't be any damage done by mixing the two oils.

To be honest, I wouldn't even dump the RP just yet. I would run it out until the first time the temperature hit -10 degrees F or so, then take it some place to have them change the oil for me because that's just too dang cold! Canada That should give you another month or so and wouldn't be as much of a waste of oil.

For that kind of money, buy some real synthetic oil -- Conklin.

If you go to the product specs on 0w20 or 0w30 Mobil 1 ~ they tend to show rotary test values (MRV and cranking tests)

Id just run a 0w in winter and until time to change oil. How much do you drive in a year? Can you use the RP part of the year?

LOL, went to have a look at their Product Data Sheet to comment on what's pretty obvious within it, and you have to create an account to view it...makes linking to it pretty hard.

When you look at their data sheets, most of it has pretty rubbish pour points and cold temperature performnace in some grades, leading one to the point of view that their 0W40 in particular IS synthetic, while a bunch of their other grades IN THE SAME LINE are more GrIII than anything else.

That's not a hater talking...that's a data sheet.

A data sheet that you have to sign up to see...

They are a joke...

Oh, but regardless...if you need -40C performance, you need a 0W...they are actually rated for that.

My car has an oil pump so I'm not too sure how relevant that video is...

I'm assuming you have some sort of pan or block heater?

I'd leave the RP in.

While I was in warranty, I preferred to use 5W30 because that was what Subaru recommended. Somebody pointed me to this cool list of 5W30 synthetic VOAs (that is, unfortunately, almost 5 years old now and hasn't been updated) and I saw that RP was not one of the stronger CCS performers.

http://www.pqiamerica.com/March2013PCMO/Marchsyntheticsallfinal.html

So RP 5W30 was about 40% thicker than M1 in the CCS test...probably not the end of the world, but I thought it could be noticeable on a really cold night during a ski trip to the Whites with my car parked outside (which I do most weekends in season). There were other things about the M1 formulation that I liked, so it was an easy choice for me to pick that over RP and even save some money.

Now that I'm out of warranty, I am very comfortable with using a 0W30 and probably will do so in December...not sure yet what I'm going to use, though. I have been keeping an eye out for the new M1 0W30 AFE bottles with a dexos1 Gen 2 license, haven't seen them yet.

I would not change it just because of the video but I wouldn't buy it again.
