Synthetic Oil

I choose to use synthetic oil because it is proven to break down at a lot longer life than conventional.

Go to amsoil.com and read the ways you save money using synthetic over conventional through longer oil change intervals. You simply justify longer intervals (amsoil claims 35,000 miles between changes although I'd never do that).

Just my $.02

I done my first synthetic oil change. I bought the PP(penzoil platinum) 5w30, I beleive next oil change I will go to 10w30 do to it will be close to summer then. I bought a mobil 1 filter also. I wished i got the bosh filter I was going to get but changed my mined before I left the store. I planned on doing the 3000 mile change then on next one go 5000 miles. I forgot about the 3000 mile oil change when i was at the store,lol. I found out I do not have a rear main sea leak its a leak a minor one above the oil filter were two bolts hold ona something with a round upward tube all metal. The oil change place said it was common in these vehicles and they did not know what the thing was were they think it is leaking at but said it was very minor and showed it to me. I changed the air filter to a fram toughguard also.

I do got to change the trans fluids and filter asap (very soon). I will do the coolant and thermostat after that soon also. Both need changing. What should I use as for synthetic transfluid and also coolant?

That's what I have been doing for years. Both my new vehicles get one oil change a year, Every fall I change the oil and filter. Last year I went about 12,000 miles on one oil change on the Sierra and over 7,500 miles on the Cadillac. I use the AMSOIL SSO 0W-30

I been using it for many years, they are a Wisconsin Company.
