I am using 5w-20. Its the rockin v6 manual.WISPER said:I wouldn't leave a 5w30 in 5,000 miles let alone 10,000 but hey, It ain't my car
What kind of car is it anyway?? I know all the honda's sense around 97' have recommended 5w30. Just wondering.
Edit: Opps, yea actually paid attention when I read this time. Mazda hehehe.
Not to bash you or the car companys, but in reference to looking at the manuel......you Do realize that the car companys are there to sell you a car, and as often as they can. I'm not saying that their trying to damage their own vehicles but running a 5w20 any anything seems pretty extreme. Especially for extended millage, under "extreme driving conditions", which, if you look at there definition, we ALL drive in "etreme driving conditions" like 75% of the time or more.Kawa-ZX9 said:The manual recommends every 7500 miles. The mazda6 comes stock with syn/blend oil. So I figure full synthetic must be good for a couple of more thousand.
Yeah, and that would be to increase the monthly gross. The premuim margin on the expensive stuff already takes care of that.brentsR6 said:in the end, it is your car and what you do with it is your business, but there are reasons why we only warranty our oil changes (cept RP and Amsoil) to 3000 miles, no matter what the make/model of vehicle or oil type.
:laonig said:So Wisper do you think the 3k mile interval idea came from independent, concerned philanthropists who want nothing to do with your money?
it would be lovely if you know what you were talking about before you opened your mouth. we end our warranty to rid ourselves of the liability that comes with going 5000+ or whatever miles people go through before changing their oil. im not saying your motor is gonna blow up cause you went 8000 miles on a conventional oil, but it does damage it. period.license2ill said:Yeah, and that would be to increase the monthly gross.
