Default 0w-20 synthetic mobile 1

On my next oil change i want to change to a fully synthetic oil. Since 5w-20 in a synthetic is so hard to find, would it be ok if i just switched to 0w-20 year round. I live on ontario so we have some bad winters here. I dont know a lot about oils, so knowledgable people please answer. If your not sure (LIKE ME), dont post wrong information...

Thanks
-LUKE

I'm running Mobil1 0w20 until I get to 10k miles, after which I will do a comparison (with Used Oil Analysis testing) of Mobil1 0w20 and 5w30 (& possibly 10w30).

In the cold 0w20 is almost certianly the best oil to use. The only question (IMO) is if you live where it gets very hot and /or you are an exceptionally hard driver where you may want to consider a thicker oil. I like where it regularly gets over 100f in the summer, I race and tow every month so conditions don't get much harsher than mine.

In short, I would definitely recommend the Mobil1 0w20 for you.

BTW, most manufacturers "synthetic" oils aren't real synthetic oils, this includes Castrol Syntec, Penzoil, Quaker State and pretty much everything but Mobil1, Amsoil & Redline (German market Castrol also but that's way hard to find)

Most (quite possibly all) 5w20 oils are at least semi-sytnetics though, generally pretty good oils. This includes the Motorcraft 5w20 that the dealer uses (is supposed to use anyways)

Edit: also this is going to get moved to maintennace & care

ryanazarko,

There a variety of used oil analysis's indicating that for the 6i/3s, heavy weight oil is not necessary to protect the engine.

Heavier weight viscosity oils are not necessarily better, and can in fact be far worse for engine wear.

If you weren't running a synthetic equivilant 20 wt oil, then I'd consider running a 10w-30 synthetic instead. Most of the pour points for the 10w-30 syn's are equivilant to 20 wt dino oils, so shouldn't cause any significant increase in wear. 10w-30 is also very similar to a 5w-20 in its amount of viscosity improvers, which are very little. Because the viscosity spread is close, less of the additive package has to be spent maintaining viscosity.

However since your in canada, you might want to take a look at your average yearly temps. It would probably be in your best interest to stick with 20 wt oils, just due to your temperature range. (Especially since most people in the hotter areas of the US are racing and running 20 wt's without issue).

If you HAD to run a 50wt oil (which is highly NOT recommended), I'd go with a 15w50 mobil1 supersyn...which is argubly one of their best oils. You'll get a rather large hp reduction and mileage reduction from doing so however, and possibly increase engine wear.

Regardless if you want to know if the oil is aiding/harming your engine, run a UOA.

well, wouldnt 5w50 be better than 15w50?
also, it seems to be that 0w30 would cover the temperature changes here best, and be a little more suitable for the way i drive. 0w20 fully synthetic is what most people are using right? so wouldnt 0w30 just be a little bit more thick/viscous so it would better suit my hard driving style, right?

0w20 Mobil 1 is pretty much the standard for us over on 6club, even for those guys who run their cars HARD (ie AutoX, track, etc).

i've never even heard of someone running 5w50 or 15w50 (though granted I don't pay much attention to that sort of thing).

My dad has a xpress lube and he said to me that it is good to stay with what the manufacturer recomend no matter the situation. For example if you are going to put 5w20 (semi-synthetic) that is what the manufacturer recommends YOU HAVE TO STAY IN THAT RANGE(if this make any sense) like 0w20 (synthetic).

No. 5w50 has a wider viscosity spread. When dealing with a wide range of viscosity, the less spread means the less improvers needed to maintain said viscosity (within the range) over time.

This is generally why mobil1 10w-30 is superior to 5w-30 in extended drains, as is 15w50 vs 5w50, etc. The oil's maintain their proper viscosity levels better then oil's with wider ranges.

Well crossbow beat me to the viscosity spread issue, but yeah, what he said.

I know Edmonton get super cold sometimes, so if you want a 0w30 I would check out some local Wal-Marts for the Made in Germany (this part is important) Castrol Syntec 0w30. IIRC, this oil has a pretty darn low pour point, and it meets European specs requiring extended drain intervals. Overall, an excellent oil from most reports, with the only caveat being that it is a tad on the "thick" side at room temperature for an oil of this type (but not excessively by any means). $6.66 a litre and seems pretty common across the country by now.

Incidentally I just changed my Nissan with this oil again last week.

Or you could go with M1 0w20, but you probably can't extend drain intervals with that...

Raitchison....thank you for your answer. i will try 0w-20 on my upcoming oil change. You helped me out a lot.

Just one more thing is there a big difference is i used 5w-30 instead of 0w-20. But Moblil 1 synthetic is my choice of oil. I it a good oil, or is there better say at a canadian tire or wal-mart...

thanks in advnace
