Clevy I believe only the 0w30 comes in signature series and yes I am using the 25,000 mile nanofiber amsoil filter.

Yeah the truck in my sig is what i'm speaking of and it has 43,000 plus miles now, this increase in milegae started last week when I went to synthetic, strange aint it...

Oh, btw the guys this is an awesome website!

My truck has averaged 13.3 mpg with castrol. Just made the switch to amsoil 0w20 full synthetic at 43000 miles. I noticed my fuel mileage going up and its settled in 0n 15.0 mpg, don't know if its the warmer weather or the synthetic? I live in south ms and the summers are hot down here...
