15w-50 a bad idea?
 

moving to Tucson, AZ end of the summer. temps wont drop below +10F here anymore...and if they do im packin up and leaving!

k03 @ 1 bar as far as turbo sys. goes...

thanks..never tried such weight..ive been using 5w-30 and 10w-30....wondering if the 15w-50 will be better for summer in AZ?

15w 50 in my car, running just fine.

Yeah.
 

Engine will really strain to pump that stuff. Mine also ran hotter. Plenty of protection with lighter weight synthetics.

How many miles on your car?
If u have over 60-70K miles then the 15w-50 is right up your alley..if u got low mileage then stick with 5w-30/5w-40/ or 0w-40

72k...73k by this friday

how much hotter would you say it was running?
 

i dont really understand oil specs that much even after STFAs. But from past experience, it seems 5w30 came out blacker than 10w30.

Ohh...Arizona heat= 15w-50 mobil 1 is your best friend

about 20 degrees
 

Enough to bump the needle. Switched to 0W-40 and it went back down. Also get better flow to the turbo when its cold.

According to your owner's manual it's alright. I use it in the summer here in Denver.

I run it on the track now. Happy with it -- oil temps down 5-10 degrees.
