Synthetic Fluids

[It\'s a Dry Heat]

This my be wrong, but I change my oil the first of every year. This year I have 3,400 miles on a 2004. I use mobil 1 extended life. Have it washed, waxed and been checking prices on detailing the inside this year.

Still loving the drive,

So, you only put 3400 miles on it this year? Or you you have a total of 3400 miles?

I use Royal Purple in most everything I own except never in differentials or manual transmissions, for some reason Royal Purple seems to need to heat up before it will let the synchros fully engage on manual transmission so for those I only use Redline. Amsoil is also a good synthetic but Royal Purple is not only a synthetic but it also has high levels of Zinc.... I know because I was having problems with turbos on one of my motors and I had a lab do a chemical breakdown of my oil to look for mineral and metal deposits.
