Oil Change coming up...
 

I'm still using delo 400 and she has close too 138xxx miles on her - should I be considering switching to synthetic even though I don't like the price?

i run schafers 2500

Price is not that bad, 20 bucks a gallon at Walmart, Shell Rotella T6..I go 1 year on an oil change, less than 10k a year typically.

Amsoil full syn and k&n oil filter costs me $165 to do oil change.

i run the amsoil aswell they say you can swap just the filter at 5k and go 5 more i have only done that a couple times. i have about 135k on mine aswell (reads 125k but had big tires on it since 60k) still the origonal injector pump and auto trans. i have synthetic in diffs trans motor and transfer case.

If you run the amsoil with the amsoil filter you don't have to change filter till you change oil 15k miles or 1 year. I run 15k intervals or one year on my truck my dads and a few others no issues. I don't understand why a k&n oil filter...

I've heard amsoil wasn't all it was cut out to be - now I'm curious.

I was thinking mobile 1...

$165 isn't bad I guess if you only do it once a year...

The only reason I ask about the K&N oil filter is I don't see it having the same capacity as a synthetic media filter like the amsoil or donaldson endurance filters

I have heard this a lot, and I believe a lot of the talk stems from other oil dealers out there and people who are still stuck on the old filtration standards and 3k mile oil changes. Amsoil uses exxon mobil base stocks. The difference is the additive packages that each company uses. A couple years ago my local diesel shop switched over to only stock amsoil and run their oil because of the differences they noticed. I have been running Amsoil in my own vehicles and have had 0 issues going with the 15k miles or 1 yr changes on my truck, and first her accord following the maintenance minder had 75k miles when we traded it in and now her crv with 42k on it now. Neither of them burn any oil and the crv goes over 10k miles between changes following the maintenance minder. I do run the amsoil filters exclusively because they are higher capacity and and smaller micron rating than factory filters and napa wix fram filters. When I first started running amsoil my dad told me he loved the oil for his 2 stroke back in the early 80's but it was hard to find. So now my whole family is running the oil. The other day a Schaeffer's oil dealer told me I should switch to them because their oil is better so I asked him how much better if any and he could not answer that. If an oil is better I would like to see some proof not the just because I said so. I don't know a whole lot about Schaeffer oil but I hear it too is good oil. A full synthetic over petroleum based oil is a step up inmho. sorry for the long post but I just had to post my thoughts.

mobile delvac and lucas to raise oil pressure and prevent dry cold starts is what i use cost about $80.00 every 15,000 miles works good :tu:
