for all those who are always wondering when you chould change your oil, here is the results of my test i had done. my driving is severe. my cars does ALOT of ideling, and over all hard driving
oh and if you havent seen my sig i have 132,000 miles

 

That was interesting and informative - thanks.

 

nice..thanx for the report..so how much miles could you have gone on that oil?

 

im guessing a few more thousand based on the TBN #. so 8 thousand on synthetic and with my SEVERE driving isnt to bad. so it should help lay to rest every one's wondering when to change the oil.

 

Thanks Kris

 

obviously the filter had a hand in this...what kind of filter are you using?

btw, thanks for posting this

 

actually the filter i was using was a FRAM i just got another supply of mobil1 filters

 

Thanks for sharing the info !

 

just a regular Fram? Or a Fram x2?

 

fram sure grip. not the x2

 

interesting....

 

ive switched to mobil1 filters so next time i change my oil ill sendd the results off to be tested again. we'll see if there are any differences?

 

I'm looking forward to them

 

only about 6000 more miles to go. about 2 months

 

Wow,
I am using Mobil 1 10-30 and changing every 4K miles, sounds like i could save a lot of oil changes and still be safe.
Thanks for the info and reassurance.

 

hmmm I guess I can wait till 7.5k miles on my TLS. I only have about 4.5k right now so I haven't done my first. My looks kinda dirty but guess it doesn't matter.:wow:

I have free oil changes with my dealer John Eagle (yes I'm weary about actually having it done there)

 

heck yea i would do atleast the 7500 mile (like honda says in the manual) and save some money!

 

I don't save any money cuz I am too lazy to do the oil change myself. I take my Mobil 1 and K&N filter to the dealer and have them do it. I break even because of the 7500mile change interval instead of the 3750 interval. The benefit I get is a better oil running in my car even if its for 7500 miles.

 

Mobil 1 is what I use. Peace of mind is worth every penny.

 

fsttyms1, did you do all 8k miles on that 1 fram filter or didya change filters?
