Who is running synthetic and is it worth the extra money?

I have 96K on my '97 and I am considering switching.

i do and i think it is WELL worth it! of all the work i ask of her i figure i can give some good oil! I run Rotella 15W40 every 5000 to 8000 miles! i dont think it's all that bad, costs me exactly $50 to change my oil, small price to pay considering all the heavy equipment i haul around

be careful though asking the syn vs dino oil question! some ppl will get real hot headed and can turn into a hot debate, lol

-cutts-

 

Why Rotella vs Mystic or someting else cheaper?

 

it's easily available, i can pick it up at any walmart no matter what state i might be in! most chain parts houses carry it and i have always seen it sitting on the shelf at heavy truck and equipment places.

where can you get mystic?

This may get ugly

 

mystic at O'Reilly's Auto. $15.99/2 gallons

 

We use alot of oil, well we were using alot of oil as I sold some of my big trucks, about 50 gal. per month in our diesel engines...........

I use shell rotella.........I have seen trucks that were using a little oil with chevron delo 400 be switched to rotella and not use any more oil................

I used mystic one time in an 18spd. tranny and it ran about 50 degrees hotter than the Hydrotex that I drained for the change...................

In my opinion it is a little lower quality oil and I will not use it...........but in a cheaper engine to replace like the powerstroke its probably ok............tractor and big truck engines I def. wouldn't use it

just my experience and opinion, not intended to offend or belittle anyone

 

i will make it a hot thread.

use only delo 400 15w-40 or your motor will blow up.....

just kidding guys carry on.
