Mobile 1 vs. Amsoil vs. Royal purple

isnt RP a lot more expencive?
not to say it wouldnt be worth it if it reverses engine wear...might try it this oil change

btw..how accurate is the oil life meter on the cts? do you guys go by mileage or that oil life reading?

I use M1 and I've made an oil analysis at 12000 km and obviously I could go a lot more and the carputer sayd 34% oil life left. So next test will be at 15 000 km ( 9300 miles). I remember that at 9300 miles the DIC showed around 16-17% left so I'll see how everything's holding on. Ghettomike, I think it is accurate but to make sure, you could do some oil analysis(30$ per test) 'cause there's no 2 same engines (metal wears etc).

i usually do an oil change every 3-5000 miles no matter what. i dont usually trust the computer to tell me how long i have before i need to change the oil.

RP around here is about $7 a quart which to me is more then worth it as i have seen amazing differences with it over Mobile 1 and other oils. (engine runs quieter, slightly better gas mileage, highly reduced oil cinsumption, and its suposed to be more resistant to thermal breakdown and along with reverse engine wear)

i usually do my oil changes at 5000km..unsure of miles... but i lost track this time because i bought the car at 113700 and i got the oil changed at my mechanic because the dp torques was destroyed.. i dont remember the km on the car when i brought it in but the sticker they put on the car says 117000 when its due at..which is totally wrong.. i think i changed it at 115000 or 116000km...im now at almost 120,000..i wanta do it at 120 even so i know every time i hit an extra 5000km its due..easier to keep track of...im usually really good at keeping on the oil changes..

also... for winter storage... do i drain all the fluids?
i want to put in better dif fluid... what type should i use? RP makes it (i think they call it redline..?maybe thats a diff company) i just dont know the GO type/weight or is there something better to use? i dont mind spending an extra $20 on the diff cuz its not like it gets changed all that often anyway and ide rather keep it in good shape.

You people (if the shoe fits wear it) go out and spend tens of thousands of dollars for a vehicle or vehicles and then nickel and dime on the oil and filters. Pick the oil you like best (any brand) no matter what the cost and stick with it. It's the cheapest maintenance you can do to your vehicle to make it last.
