Hi everyone! Thought it'd be fun to see what kind of oil and filter everyone uses in their 4.9
300 straight six?


I use valvoline synthetic, or penzoil synthetic and (used to be fram high milage
Filter) not after what you guys shared w/ me today I'm going to switch back to motocraft.
Everyone else????????

 

a man's choice in oil is much like his choice in women: it is strongly held to but supported little (if at all). i use house-brand (carquest, auto-value, napa, whatever) oils and have never had an engine failure that related to lube problems, so i'm more than satisfied.
as for synthetic, i've chosen not to, as synthetic has a bad habit of getting through that protective layer of sludge that used to prevent leaks, which then leads us down a path of chasing leaks.... even though it is a better lubricant

 

I use Castrol/GTX, 10w30 - 96 Mazda PU with 298,000 miles and a Fram TG filter, daily driver. 94 F250, 5.8-C6, 160,000 miles. 10w40 Motocraft filter, work in progress(why I joined this forum!) also 03 Nissan Altima 224,000 miles, GTX10w30 Owned the Mazda and Nissan from birth! The F250 hauls the horse gooseneck.

 

Good ole Castrol GTX 5w30 in the winter/10w30 in the summer....With a nice Motorcraft FL-1A.......Can't beat it...

 

i use whatever ford puts in it
motorcraft prolly

 

Castrol GTX 10w30 , K&N filter....

 

they put oil in these things? havnt changed mine in 10 years.

 

jk i use the cheapest synthetic i can find. sometimes ill create my own synthetic blend (1qt synthetic for every 1 qt conventoin) depending on whats accessible and not bein used around the shop(s). i cant justify spendin tons on the oil i put in the beaster, but i just cant drive myself to put all conventional in there. makes me sick.

 

I've always ran Valvoline or Shell Rotella T in my Diesels, witchever of those 2 are on sell, with a Motorcraft or Wix filter.


Always Valvoline in my gassers with Motorcraft or Wix filters as well.

 

Castrol GTX and Fram filter. (Never heard anything bad about Fram by the way, do I need enlightenment?)

 

Yes you do , just google oil filter tests....

 

^what he said. . . fram has a major come-back ahead of them if they wanna be a leading filter company.

 

Have a good read through this, and watch the vids posted!

this is no joke guy in town owns 2 cadilacs 1 1500 and a corvett doesnt change oil in anything just the filter lets it drain out and poor it back in he said he goes through a quart or so every 15000 miles maybe 1800 says that oil never breaks down just gets dirty

but anyway on dads and my 300 we use rottela t 10w30 and a two quart filter when its the middle of summer its 15w40 rottela
on the 302 tropartic and a fl1a

 

this opened my eyes!!!!!!!!! thanks to a certain forum member i will NEVER EVER EVER BUY ANYTHING FRAM AGAIN!.........i used to only run fram untill i saw this
