Well im switching to mobil 1's new formula good for 15,000 mile intervals. time to dump the 8000-9000 mile intervals in favor of atleast 15k

 

I run Mobil 1 full syn.....and love it

 

so do i, now im upgrading to their new formula that allows more miles

 

wasn't their another thread about this new formula?

 

If you use a Mobil 1 filter, would you only need to replace it every 15,000 miles too?

How much more does this new formula oil cost?

 

Yeah unless they make a 15,000 mile filter, which I highly doubt, how are you going to address changing the filter?

 

Turn the car upside down to change the filter?

 

just by removing the filter at 7500 and sticking a new one on. you will only loose the oil thats in the filter

thats if i decide to change the filter durring it

 

I just change it when it the oil is dirty. Don't really go by the numbers

 

How does using Synthetic for extended intervals effect warranty coverage? (Just to CYA, my warranty says not performing 'regular maintenance' is grounds for dropping coverage, so I'm concerned for myself )

 

no how can you tell its dirty? the color? that doesnt mean any thing, or that its dirty.

 

that wont effect warranty unless that is PROVEN to be the reason, or cause of what ever the failure is. ive been running extended change intervals on the TL for 171,000 miles now. no issues whatsoever, no burning no nothing. and now its gong twice as long between changes!
