You crack me up......Gee, my oil tests are better then the 5w-30 and Lexus does not use 5w-30 anymore. Oil in the manual is a JOKE. They are behind the times. Example, I need an SL rated oil...give me a break. Plus you can use ow-20 in place of a 5w-20/30 and be 100% fine. Hell, I use 5w-30 in a diesel engine that calls for 15w-40; which is too thick.
Again you and others in the forum/thread THINK 3 to 5 K miles gets you something. Prove it with showing me the data? You nor anyone on this thread can since you are all guessing; that is a fact here. I know how my engine is running and oil duration etc is a benefits. Which you all are lacking.....Again fact and I have stated that many times. If you are not testing you are guessing on oil performance.
Oil consumption has nothing to do with oil weight! See, you need to stop posting on oils since you are posting BS. Fact here
well you dont have to be a smarty pants, oil is cheap, fun to change, and easy to deal with. The thinner stuff gets hot, and will boil if the motor heats up enough. trust me I know man. Stop tellinf me I am posting Bull*BLEEP*. I can post what I want, try stopping me. I am a member and so are you. We are aarguing over oil, its 2 buchs or less a quart, big deal. Did you make the engine, noo toyota did. Who puts 0w-30 in their motor. ONLY YOU DO. YOU ARE THE FIRST PERSON TO USE THAT CRAP THAT I HAVE EVER SEEN. that stuff would suck. do not put the bozo clowns recommended oil in your car. he wants to see you come here *BLEEP*ed off. Until I find this oil thing works, i am going to be arguing here. If it works, I will beg for some forgiveness.
:D sorry if i am sounding like a moron
you should listen to mburnickas, he knows more about oil, gas, additives, and the 1MZ (amongst other things) than I or you could ever hope of knowing. for the record, I run GC 0w30 Euro oil now with Lc20 (thanks to mburnickas) and so does just about everyone I know in every kind of car. if your car is boiling 20 or 30w oil and it's a toyota/lexus your engine has problems. I drive my ES harder than you could possibly imagine when I drive it, and my engine is sludge free and clean as a whistle (I also have pics to prove that) and my car has done 131K miles. I run 0W30 GC in all my cars, and swap oil every 5000-7500 miles with my mobil1 filter, once I switch to the Amsoil filter, it's going to 10K miles. please, please listen to mburnickas who is only trying to give this guy some proper advice.
sorry if that was at all harsh, I'm just giving my $.02
