I took it in and had the timing chain cam phaser and solenoid replaced.
Fixed some of the startup but none of the accelerating.
Any ideas/suggestions? Thanks.

I put in 5w 20 and am wondering before I try 5w 30 if anything else could be to blame. My opinion is that the previous owners took very poor care of the truck. So i have ran some rislone engine treatment with the oil and changed it(black) shortly after. Any ideas/suggestions? Thanks.

From what I have gathered, the recommended oil that is 5w-20 is geared more toward appeasing CAFE standards set by the government. These standards have almost no bearing on the engineering side of vehicle production and are only in place thanks to ideological opinions that want to leave their mark on society and of course, collect their paycheck. In order for a manufacturer to sell a vehicle in this society/economy, they HAVE to adhere to these standards created mostly out of "popular" consensus ideas. These ideas deriving from a biased education that "means well" but has only 1 side of a 3 sided story. Where they got there education or "conditioning" is a whole different story. These adults have one goal before the work gets done, that goal is to keep themselves RELEVANT even if society no longer has a use for them. It is just how our society and economy tends to work. Under these conditions I find that the 3rd side of the story almost always gets "lost"....the 3rd side of which is the TRUTH.

Corporate Average Fuel Economy or CAFE is the reason why 5w-20 is the new north american choice. Other economies and country's are using 5w-30 in the same engines that reside over here, demanding 5w-20. Of course temperature and location reflect some of those differences but certainly not on the broad scale you see over here in the USA.

My argument and question is this

I like the slightly better wear characteristics of 5w-30 vs 5w-20, the two are the same at cold and one is slightly more viscous at operating temp. I personally want my engine to last as long as possible and will sacrifice the undetectable mpg loss for better wear characteristics.

Who is using 5w-30 oil in their 5.4 3v?
Why are you using 5w-30?
What results or differences have you noticed while running 5w-30? Like less VCT ticking or dieseling sounds?

Who is actually running 10w-40 as recommended by Oasis special service bulletin #21217??? http://www.bobistheoilguy.com/forums...Number=1897871
Why so thick? 10w-40 is a way thicker then 5w-20, shouldn't that cause more problems due to the wait time on the initial cold flow? and then the viscosity after warm up?

I'm very curious and also trying to come to a final conclusion here.

THANKS!
