I HAVE ALWAYS USED 20W-50! IT'S ALSO WHAT THE BOOK,(OWNERS MANUAL) CALLS FOR IN 90 DEGREE WHEATHER. BRANDS? VALVOLINE, MOBIL ONE(IF YOU CAN AFFORD IT). RIGHT NOW IAM WORKING CASTROL GTX RACING, WHEN THE TEMPERATURE GETS ABOVE 100 OUT HERE IN THE CENTRAL VALLEY, THE CASTROL STAYS UP AT 45 PSIG. AND I HAVE YET TO HEAR ANY LIFTER NOISE FROM THINNED OIL. THE 20(WINTER)(ADDITIVES,DETERGENTS,SUSPENDERS, ETC.) PART IS TO KEEP LIFTER,(AND OTHER PARTS)"VARNISHING" TO A MINIMUM!! THATS THE REASON I DO NOT RUN STRAIGHT 50 WEIGHT IN THIS HEAT. REGARDS, MARLIN.
I use Mobil 1 synthetic, 15/50. the Mobil 1 website has the following recommendations:
Mobil 1 with SuperSyn� is available in five viscosity grades:
Mobil 1 with SuperSyn� 10W-30 � Higher-Mileage Vehicle Formula
Mobil 1 with SuperSyn� 5W-30 � Newer Vehicle Formula
Mobil 1 with SuperSyn� 15W-50 � Performance Driving Formula
Mobil 1 with SuperSyn� 0W-30 � Enhanced Fuel Economy Formula
Mobil 1 with SuperSyn� 0W-40 � European Car Formula

I run the Mobil 1 15W-50 also, with a Purolator PureOne filter. Check out www.minimopar.net/oilfilterstudy.html for additional information on filters & oil types. Probably the most thorough study done to date. Keep the shiny side up!
