PP 5w30 vs 5w20

[Ndx]

Hi Guys,

Another question Car is speced for 5w20 Can I use PP5w30 its more available ... WM don't cary 5w20 in Jugs

Thank You for help

If this is for your mazda3, the owners manual says you can use 5w-30 if 5w-20 is not available. (Mine does anyway) I use a 30 weight in mine because the engine is smoother.

Oh really .. ? I don't have anything like this in my Manual ...
Maybe because my is 2004 ?

Thx Anyways.

How do you like that Valvoline Syn ?

I would just used what it is speced for. See you live in Canada, its not like you are dealing with AZ or TX heat.

Well today is 30C!
Beside its not really about heat.. Its more about Price .. and availability...

If 5w30 is safe same as 5w20 I rather get cheaper 5w30 ..

5w-30 will be fine. I like the SynPower, and the price in a 5qt is right. Not much difference from PP, in the Highlander.

My 07 Focus is spected fo 5-20 but I use M1 5-30, Because I'm set in my ways. Also Mobil tech said 5-30 is no problem for the Focus. It's a cafe thing.

I would say so. The only downside might be slight decrease in fuel economy, but it's probably small enough that you won't even notice.

I also prefer 5w-30 (or even 10w-30 during the summer) in my 3.

The flow properties of a synthetic 5w30 are very similar to a conventional 5w20. As long as u are using synthetic ur engine will be extremely happy. If u wish to run a conventional 5w30, then i would only do that in summer, but synthetic 5w30 is great to run all year. for example, do a google search for Pennzoil viscosity
and look at the cold MRV etc and compare synthetic tables and conventional tables and you will see what i mean. the engine does not read what is on the label, the engine only knows the physical property of the oil, and the physical cold property of synthetic 5w30 is a match for physical cold properties of conventional 5w20.
Once the oil is at operating temperature, the difference between
cSt of 8.5 vs 10.5, to an engine, means absolutely nothing, a very very minor change in viscosity that will mean the difference of a tiny fraction of a mile per gallon.
WalMart does carry the SuperTech 5w20 synthetic in jugs, and that is what I would use in the winter, for PHENOMENAL cold performance.

The PP 5W-30 wouldn't hurt anything. But they do have 5W-20 PP in jugs here in the states I believe. I see you're near Hamilton and could always perform a cross border raid.

And Motorcraft syn blend 5W-20 is also excellent. Is that available?

If price is a concern, why not just run a conventional 5w20 instead of synthetic? You could get a 4.4L jug of conventional 5w20 for around $15 on sale up here.
