i see an over abundance of information on this thread...
K.I.S.S. (keep it simple STUPID!)
when your oil gets dirty that means your filter is done(all the oil is bypassing the clogged filter) SO CHANGE EM BOTH!
this 3000 mile crap is exactly that... CRAP!
and use a good filter that actually filters oil... FRAM IS CRAP! http://www.youtube.com/watch?v=KQahONrRwHQ
fram and pennzoil... the two engine tools of destruction http://www.youtube.com/watch?v=rfW8W3sjbto
really, you wont notice any difference between synthetic and dino oil... i just tore into my engine after using mobile 1 for 30k miles on a motor that had 150k miles to start with... (timing chain worn out)
now camshaft wear = perfectly fine! nothing wrong with my flat tappet cam! anyone wanna chime in here and make up some crock and bull story about synthetics tearing up camshafts be my guest... i know you are wrong!
i do like the fact that the sludge was slowly but surely being removed from my engine since i got a hold of it and actually changed/ inspected my oil regularly... you can definitely tell where the sludge has settled and where it has melted off of most of my internals... like for instance the intake plenum... that pan underneath it is completely full of sludge, but you can look in my crankcase and wont find a lick of the crap...
on a side note, i did notice that i have a camshaft bearing that either spun or was improperly installed because the oil hole is about 30* off but thats my new problem and dont attribute that to synthetic oil.
wix 51036 filter = $4.22 (rockauto)
valvoline 1qt = $3.69 (local farm&fleet) with this you have to pay a common sense fee of $0.10
fram ph3980 = $4.12 (rockauto)
pennzoil 1qt = $3.69 (farm&fleet) with this combo you get FREE engine wear!
oh, and just noticed the OEM ACDelco PF52 is only 2.98 on rockauto...
edited to be back on topic....
anyway, you probably wont know a difference between dino oil and synthetic oil. just run the valvoline regular and a good wix filter...
dino oil has been around forever, never really had any problems why change something that works perfect
