I was at walmart and bought a 5 qt container of Mobil 1 Fully Synthetic Extended Performance oil for 26.48. Went to dealer and got a filter for 3.75 (special!!!!)
I asked the dealer about the myths of synthetic casuing leaks, and like the forums here, he said they were bogus myths from the non-believers! I asked him if there was a specific mileage about the oem oil filter because the M1 was rated at 15,000 miles. He told me that the filters would have no problem with that milleage. So i am going to be watching the oil condition and see when it starts to change color around 8-10,000 miles, hopefully it will make it to 15,000!
It feels wierd to say your gonna wait to change your oil for 15,000 miles!!

I figure I will save well over half of the cost when you add the filters and only have to change it once instead of 5 times!!! STOKED!

i go 10K on the OEM filter...no problems. has anyone seen the Truck/SUV blend of Mobil1 Fully Syn? I picked up 6 quarts and am going to try it next change.

Why would i go get a toyota filter when they put crappy oil in cars. Do they have a realy good filter because of this? Who says its any good?

To get that sort of mileage from your oil, you should consider changing your filter halfway through your oil change interval. In other words, change your oil every 12000-15000, but change your filter every 6000-7500. The oil changing color is not a good indication of oil being ready for a change in a combustion engine, because engine oil darkens quickly... it doesn`t mean it is no good anymore.

I just swapped out my oil to synthetic so that I could do annual oil changes. Did a lot of reading before biting the bullet and it was recommended to change the oil filter at about 5k miles. I didn't want to bother so I found out that Amsoil has a 25k filter and used this instead of OEM.

Before I get flamed, I will not wait 25k to change the filter or oil. I will do this annually and since I drive less than 10k miles in a year, I'm pretty comfortable w/ this interval, especially considering the oil and filter I am using (both Amsoil). It also gets me to a mechanic less often, hopefully.

I'm ashamed to say this, but I have no idea what mileage I changed my oil last. Therefore, I have only the vaguest idea when to change it again. This is particularly irresponsible of me because it's Royal Purple synthetic, a $60 oil change, lol.

i don't like my oil and filter to be in the truck more than a year so I either got to a year or 8-9k when I do my change.

I too use M1 Ext Perform, but w/ the M1 filter as well. I do 1 yr or 10k miles, or which ever first (always 1 yr). But I change the filter and top off at 5k miles or 6 months, which ever first.

In my 01 ,2.7 4x4 I have been useing synthetic Mobile 1 for the past 3 years. Flushed out whatever oil was in it when I got it and started useing a fram filter and just did my third oil change with no problems at all. My average yearly miles have worked out to 8,700 mikes and I change the oil and filter around that time.
The engine runs as smooth as butter with no valve noise no matter how cold or how long it sits. Always do a grease job about 3 or 4 times a year because of so much off road and water driving. Love my TOY!!! Mike
