smh
this kills me!! everyone talking so highly of 30 wt oil.. and engines that were calling for this in the 90's, if you really want to do your engine a favor use a 5w40 or 5w50 synthetic, or 10w40 conv., engines now call for 5w20 for the gas mileage, there is nobody that can show any blueprint to prove engine tolerances are tighter because they are not, I have 01 Honda civic that calls for 5w20, though all its life it has had 5w40 synthetic and still runs like a top, doesn't use any oil between changes and just turned 201,000 miles, also a 2003 ford escape that calls for 5w20, same for that 5w40 syn. has 198,000 miles, no oil consumption. and have 2007 dodge caliber r/t with 2.4liter it as u guess gets 5w40 not as many miles on it but has 120,000 and has always got this oil wt.,
my dad while I was growing up with 2 other siblings for years as the more "family" car had 1989 chevy celebrity 2.5 liter 4 cyl that in summer months got 20w50 and 10w40 winter, had 260,000 miles as he had purchased only year and half old, that engine sounded great with no engine noises never burnt any oil! and further more anyone that ever has had any familiarity with those 2.5L "iron duke" gm engines know they bang and clank like crazy after lot of miles, this one still sounded new and nobody ever believed the miles until they saw the odometer themselves then would say you just put a new motor in.. and would say to them no its the original!
I will say this.. I'm 33 never used a 20 or 30 wt oil ever, and for all those that think its horrible and your gonna blow the engine or whatever bad horrible thing that's going to happen, it hasn't and it wont, I have seen proof positive it works great! the CAR MANUFACTURES don't want cars lasting a long time, that's less they sell, so yes that's why you hear horror stories of using heavier oil because those are the ones with the horror stories or its someone with a horror story that was told to them by another person that is mechanic at dealer or works for dlr or is someway connected to dlr or manufacture, just something to think about, fyi my great uncle worked for gm in michigan until retiring and moving back south, he didn't tell a lot of ppl he used heavier oil, but I never saw him with a 30 wt oil, I always saw him with 10w40
