Looking to switch to a 10w50 or 15w50. Been running 5-40 but I'm finding it too thin and I'm burning it now. My owners manual calls for 5-10-20w50 in summer.

Only oil I've been able to find is castrol 5w50 edge.

Any other options for oil in Canada? Thanks guys.

How much is Edge 5W50 there?
 
Petro Canada (Suncor) has new 15W40 and 20W50 Duron Classics.
Another option is any of the SAE 40s like Chevron's
Delo which is the good 'ol high saps blend.

I would imagine most group III 40s will pass 25W
as might Mobil's 1600, which may have a shot
of PAO...just to get the fluid dynamics in check.

The SAE 40 scale takes up more space
than any of the other grades.

On the light end of the 40's, 20W40 is quite common.

Forgive me, but synthetics in maudite hot weather
maketh no sense to me.
Sans plastique svp.

(Oops, I didn't notice Maple Ridge up there.
Sorry about the train whistles mate, there is
one crossing after another, mile after mile,
and it drives us crazy too.)

Normally 53.99 for 5l, I got mine for 31.99 on sale.

Depends on where you live. British Columbia has Chevron.

Mobil1 has 15W-50 available everywhere Canada.

Maudite hot weather.

I almost peed myself.

Awesome.

Anyway op if you are burning a 40 grade I'm betting your rings are coked up. I'd try a piston soak first then if that doesn't help then go a grade thicker.
Ford has a 50 grade for the track pack mustang. Maybe it'll work however historically 5w-50 shear out of grade pouring out of the bottle and the 40 grades retain their viscosity better.
Unless you use a 20w50. They hold their grade well in motorcycles,and loads of anti-wear agents

Redline 15w50.
It's expensive, but bulletproof.

Is that where Vancouver is? I went up there on the boat. Beautiful place.

Thanks Clevy, Maudite was the beer I was drinking that
inspired the post.

That's twice I got ya.
The last was my association of adult diapers
and old cigar smell to Cadillac.
 
I'm currently running redline oil (5w40) and that's when the oil burning began. I was running T6 for the last 2+ years. With the T6 I consumed about 1qt every 5000km. That was normal oil consumption. I switch to redline and so far in 6000km I've used 6L of redline and another 3.5L of rotella t6 for topping up.

Probably going to stay away from redline after this.

Hey Morris400 – For your Audi S4, we recommend Shell Rotella T Triple Protection 15W-40 motor oil. It provides the correct viscosity for your engine as well as higher amounts of zinc anti-wear agents which is good for older engines. Shell Rotella T Triple Protection has approximately 1,200 ppm of zinc (versus about 800-900 ppm of zinc in current API SN/GF-5 motor oils). Hope this info helps! – The Shell Rotella Team
