Syn oil is the best you can use for any eng. there is no carbon build up.
I changed my oil on my 04 when i got it home and could not beleve it the factory oil that was in it. was like water. When you change your oil with syn, make sure you use a good filter. also your pressure will be a few pounds more, nothing to worry about.

ive used valvoline full synthetic on every ride ive had. im gonna go mobil one with this one. i got 6 quarts of the 5w30 ready right now. i usually dont keep trucks long enough to get the benefits of full synthetic, but i might have to keep this one for a while. so mobil 1 it is. :head:

Wix is a good filter, I get mine at O'reilys. Carquest premium filters are good too (made by wix). Don't use fram, they suck.
Just switched from Pennzoil to Valvoline in mine. I'd think about synthetic, but I have 165,000 miles and don't feel like messing with any problems that might arise from switching.

They dont use high dollar syn oil in a brand new truck because you are not supposed to break an engine in with synthetic...its too slipperyStocklook said:

Here's what I do to new motors... (depends on if off dealer lot or built then installed)
1. Change oil ASAP when comes from dealer or after the motor is first started and oil pressure confirmed. There is a LOT of nasty crap in there.
2. With new oil in after first start or taken from dealer, go drive about and romp the motor a few times to help seat the rings also put it in a manual low gear such as 1st or 2nd and give it about 60-80% throttle and do not upshift...let the vehicle slow down via drag/resistance (vac) to seat rings. Vary driving habits.
2. Change again around 500 miles, still more crap floating about in a new motor as bearings/rings seat properly. This is cheap insurance for your motor.
3. Change it again around 1500 miles, same rules apply for 2. Just drive normally avoid excessive beating of the motor.
4. Lastly at 2500 miles consider your motor broken in, then is when I'd switch to synthetic. And if you go to syn, do NOT change it at 3-4K...it's a complete and total waste of money. This stuff lasts and lasts. There's some in my mother's LS400 with ~2800mi that looks NEW still.

It makes me wonder if anyone actually knows anything about oil. The difference between 10-30 and 5-30 is the viscosity of the oil at hot running temperature.
The first number (10 or 5 in this instance) is the viscosity of the oil at peak running temperature (operating temp.) The second number (30 in this case) is the viscosity at cold temperature (like in the morning after the truck has been sitting all night).
10/30 synthetic and 10/30 petroleum based have the same viscosity. One is natural, one is man made.
Depending on where you live, depends on the weight of oil you should be using. Look in your owners manual (yes it's there) to find out what the manufacture recommends for what temperature ranges.
Oil filter play a major part in oil's performance. Why buy a cheap no-name filter if you're going to be spending $20-$30 on oil? Do your research. You might not want to change the oil every 3k (synthetics are made to run 5k-7k depending) but filters are not. Change your filter every 3k and just top off your oil as needed.
