Switching oil
I just know it made 30 degrees difference on my guage in my trans running full synn - All the proof I need
Either theres allot of oil manufactures out there that mislead and false advertize to everyone in the world ..
Or it's just some of the info in this thread..

Wow! Can you guys go at it over the free air vs nitrogen in the tires issue? Or is that in another thread? A little more for oil I can see. Paying for nitro in the tires if its not an aircraft or race car.......just plain money burning to me.

I still use Castrol GTX 5w-30 after 185000 km's and it's the same as at 40000 km's, oil is oil, only concern should be the weights needed.

I don't want to hear because my engine blew up, gotta blame something stories, just real fact. I change my oil regularly, use a few different oils and filters and never had a performance issue. The only thing I didn't like was some ends were just too big for my filter socket so removal was a bitch.

That's what I've used Castrol GTX 50/50 5w-30 for 210,000 . I tried switching tp Amsoil once - but was met with a seriouse case of blow by for some reason - change back and it's fine again..
Fram oil filters are missing something inside that the Motocrafts have , something with the valve , I can't freakin remember exactly, somethings different.
Absolutly stay away from there fuel filters - I tried them once... -

Boy did that son of auh B cheese me off!!!!!!!!!

Edited for misinformation...The Fram oil filters have a cardboard seal, not a cardboard anti-drain back valve. My mistake. Either way, cardboard isn't the best material to use in high heat applications. It can get brittle and fail over time.

Hell, even if you do seep a little oil it will still the price savings could pay for the oil to replace it and you would STILL have money left over.
OIL= 2.89/qt X let's say 5 qts. = 14.45
"MAX LIFE OIL" i may be wrong but i think it's ~3.68 a quart
X 5 qts. = 18.40
difference = 3.95
it's obvious that a brand new engine isn't going to leak due regular dino oil for a while so let's say you get 10 changes before the seals start getting "old". that's 39.50 that you get to pocket. So now it starts to leak lets say a quart between changes. (I know, a little extreme but I can still prove my point). so with the money i SAVED from not spending extra money i can buy an extra quart to add between changes and come out ahead in the end.
3.95 - 2.89 = 1.06
so in the worst case I am saving 1.06 per oil change. Some engines will leak no matter what due to poor design. I have yet to see a reputable engine (not an engine like the 302 that are notorious for leaking out the rear main) leak oil with dino oil and see the same engine that was run with "better" oil NOT leak.
The 1.06 will add up over time.
If any of you feel you have 1.06 to just throw down the drain, tell me and i'll give you my address

Raise your hand...

I love the whole "high mileage" oil image. "It's formulated to provide extra protection for those worn out 70,000+mile trucks" Well if it protected it better, why not run it when the truck is new! Oh, and what do they make for the REAL high mileage engines? Like mine ....(204,000 miles)

I don't have the money to cut open 30+ brands of oil filters much less the expertise to diagnose oil filter engineering. YES, I was told this and that, reasearched it online and with local shops and made up my mind. I will stick with WIX.

that's why i've seen cars go 300k on the same ole' plain dino oil and viscosity that was used when new.
