Originally posted by JohnBrowning: For summer use M1 15W50 has always worked well for me in every Toyota we have owned. This does not mean it will the best oil for your application. It definately will not hurt it any at all. My family has owned one of just about every engine Toyota has ever made. Your 3.4 V6 is one of the few engines we have not owned! As a mater of fact my Moms Tundra 4.7V8 has M115W50 in it right know. My Dads Tacoma also has 15W50 in it right know. I have Redline 5W40 in my Camry 2.2L.

Originally posted by Al: Its too thick. You'll loose HP and fuel economy in normal driving. You could mix as was suggested or better yet Delvac 1.
quote:Yes, Although I have not used it myself, I get it on GOOD authority (several sources) that Delvac-1 is a Top of the line motor oil... one of the best for many applications. As far as your predictions, I'll bite and go with the Delvac-1, but do a real good test and go for several drains, keep the filters clean, etc...
Originally posted by JohnBrowning: Hard to go wrong with Delvac-1 but I have not tested it in a Toyota yet! *-*-*-*-*-*-* I am predicting that Redline will out perform Delvac-1. I am only going to use UOA as my judge of performance. *--*
quote:Three, Three, Three on each (oil change), perhaps FOUR to be sure. Then you are only part sure because environment and copnditions and parts are changing/wearing etc. but yes,IMO - do several OIL CHANGES to get a good confirmed report with several UOA on each, that's the only way IMO to have an educated opinion.
Originally posted by sprintman: JB one run of Redline (5W40) and single UOA is pointless as many previous posts here confirm. Trend analysis is required. Why not 2 or 3 with RL then try Delvac 1?
