I am only going on the 9th of 12 free oil changes from the dealer, so whatever they put in it, is what I am running...

 

I will be switching mine when my 300 is up, that's for sure. What a good thread BTW

 

I'm going to be changing to syn next oil change, which is soon, just not sure which one, so many opinons, just like an a@#hole everyone has one. I'm looking at Mobil 1 high mileage, my truck just turned 100,000 + a couple.

 

*3000 miles not 300

 

uh huh saweet deal

 

Oh no offence meant, just that there's so many opinions it's hard to decide, but I do know it will be SYN.

 

no offense taken here dude : )

 

I have used Valvoline synthetic in my 2005 Dakota since it hit 5,000 miles (now 63,000); Same with my 1993 4 X 4 Suburban (now 162,000); Used it in my 1985 Jeep since it came out (now 121,000); In my wife's 2,000 Mustang (now 59,000). I also use synthetic for all fluids in everything. No oil consumption, or wear problems to date. I'm sold. Just MHO.

 

yeah i use Valvoline Max Life SYN...used it in my 96 Dakota and i got it with 20K and i sold it 200K and no cracked seals nothing leaking! so IMO Valvoline Max Life Syn the way to go!

 

Bought my '04 4.7 with 21K on it, had always had had conventional Valvoline used up to that point. I started using Valvoline Synpower; no problems, however, no difference either as far as gas mileage or engine noise.
Been using Schaeffer's 9000 full synthetic last couple of changes. I like the idea that it has microscopic molybdenum disulfide, a great lubricant. Again, tho, can't say I notice any changes. BTW, no oil consumption at all with any of them.
Just bought a '13 Grand Caravan with the 3.6, and it calls for 5W-20, so I'm using Mobil 1 since I can't get Schaeffer's in that weight. Just feel safer with synthetic, especially when I have to use 5W-20, which is about the same as 3-in1 sewing machine oil.
