Synthetic Oil, 12 Years later?

[CanadianDiesel]

Bought my first 15 Liters of Synthetic 5W-40 Oil today...but was wondering this:
Since it's the engine's first (that I know of) Synthetic Oil batch it's ever seen, will it still make a difference? I'm not talking anything crazy performance wise, but will the engine be "happier"?

[7.3Lariat]

Well fresh oil always makes an engine happy. I am in the same boat about to throw 5w40 in for what may be the first time.

[CanadianDiesel]

Yeah fresh oil is always great but I'm just wondering the difference between 15w40 and 5w40...if ever I buy new it will get synthetic from the first change

Well it s hould start a little quicker and smoother cold, and it supposed to help with tired injectors. Other than that, it should run about the same, maybe just a little quieter as well.

Oh yea! Go from 15/40 dino to 5/40 syn, your injectors will be noticably quieter.

When I did the switch in my 99 I also did a batch of diesel clean and 2stroke oil. It was REALLY quieter. Figure that was the first time in 161,000 miles anyone has ever addressed the oil or the fuel side with quality.

It was from really rattely to almost as quiet as my 6L.

Power wise, of course your not going to notice any gain. But she will be happy on a winter morning!

The best part is, it will start if it's really cold and you won't have to worry as much about being stranded in the mountains 50 miles from an outlet.

We had a cold snap last year and I left a bottle of Rotella dino outside with temps around 10f at night, man that stuff gets pretty heavy in those temps. I can't imagine how it would be in a really cold climate like Alaska at -30f

Yea, at that temp, I would have to plug my truck and myself into an outlet!

I kinda like cold. Somthing great about a hot cup of coffee, 0 degrees out and a truck that is fun to drive in the snow!!!

You've got me beat, I'd have to plug myself into the first flight to Honolulu.
