Like i said i see trucks with over 200k miles on them knocking every cold startup. Mine does it when its around 40 degrees and gets worse the colder it gets but it doesnt worry me, i just let it warm up a few and no problems. Dont lets these guys freak you out its is common and it will take a long time before any real damage will happen. Listen to the ford triton engines if you want to feel better they still knock after being earmed up especially if they have cam phasers.01' 1500 LT Z71 ECSB 5.3L

Sur, thats an old myth that synthetic will cause leaks. Not so. I've researched this topic a LOT, and I now use full synthetics in all my engines, '93 Dakota, etc., uses nary a bit of oil. I'd change to synthetic.That old man, he don't think like no old man.

- River Ridge Louisiana-4 miles W of New Orleans-didn't flood-water stopped 800 yards away.
The old myth "bad to switch to syn on old motors with lots of miles-leaks etc"
Started with a grain of truth in the late `1970's with one of the 1st synthetics
Arco Graphite or Arco Graftex(forget the actual name"
It was an EXTREMELY thin base synthetic with graphite suspended in it.
Back then seals gaskets weren't as good-plenty were probably cork and cardboard or rubberized cardboard cork
And this new oil was THIN.
When this oil-even a little of it-slipped past a gasket-it PAINTED the engine carport garage floor-
EVERYTHING got crapped up with this jet black crap.
Ever since then-the myth "don't use Syn on old motors" has been repeated.
Well-this is my guess on how the myth started-
had a buddy-put it in his XS500 Yamaha MOTORCYCLE- outside motor looked HORRIBLE-so did his pants etc.
I also used it-it was good oil.1998 suburban-

I've gone straight to full synthetics on all mine, nary a problem with seals, and like I said, using it in my oldest, '93 Dakota. This is not just anecdotal, much research into my decision. Use synthetic.
