Mike and Dargo,
First I respect the heck out of both of you, your knowledge, and opinions. I share many ideas with both of you.
I have a few points to add.
Warranty means the mechanic gets paid 1/2. I used to look for any way I could to void a warranty. Just to put food on my table and pay my tool bill.
Mike your Vehicle service practices (synthetic oil, oil testing, etc) are exemplary. I feel the same. I have no doubt that your methods work extremely well. You will never have an oil related failure.
Drago you know the way AUTOMOTIVE dealers and manufacturers are. They will get out of paying if they can. I've seen it many times. Even if they have to pay the labor is 1/2.
Mikes oil is better at extended intervals than junk at short intervals. But manufacturers will look for a way out.
Now this is the first go around I have seen between 2 Pro synthetic guys. We all need to regroup and get an old fashioned synthetic vs. dino rumble going. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
edited to add the word automotive in front of dealers.
