ENEOS oil: power adder or snake oil?

[DSM_421]

I could never let my self go 25k without changing the oil. Although I would hit the 1 year mark (where AMSoil suggest changing) before hitting 25k miles. I guess maybe this summer I will only need to change my oil once, since I put on less than 10k in a summer.

and kracka i believe what blizzard has to say about the amsoil getting better gas economy.

like i stated before my pt cruiser usually gets like 22-23 depending on how i drive it(not much change day to day)...

when i switched to amsoil i am now getting 25-26...i believe it has to do with how thick the oil is when you start it up and the lubricting properties it has at 40 degres and below outside!!!

if you take a bottle of castrol and a bottle of amsoil and put them in your freezer overnight and poor them out the next day the amsoil has thickend up at all, where as the castrol looks like lucas on a hot day!!!

that and the fact that castrol is only rated to 5k and amsoil is rated to 7.5k with a standard filter and 15k with an amsoil filter my play a big part in the difference of blizzards numbers...:)

i know, i know, i have way to much time on my hands to learn all this crap....

AMSoil and their filters are rated until 25k or 1 year, whatever comes first. I don't believe it has been rated for 15k for a couple of years now.

But Kracka, is all mobil 1 a full synthetic or only the 15k extended life? I think thats what they call it.

[Kracka]

Mobil 1 has not been a true 100% synthetic in North America since they lost their court battle vs. Castrol. I do not know much about their Extended Life, High Mileage, or any other niche lines. Do not take this info the wrong way though, Mobil 1 is still a very good oil. Mobil 1 and Castrol Syntec are both among the best off the shelf synthetics available; Redline and Amsoil are among the best specialty synthetic engine oils. I currently run Mobil 1 in my Evo since its factory fill, that may or may not be changing in the near future, I am undecided about Eneos yet (but its not lookign good) and I'm also considering Syntec. Until the Evo I never ran synthetic engine oils since conventionals have come a long way recently and offer terrific protection.

Oil generally wears out due to the additive package breaking down, not the oil becoming dirty (assuming you are using a quality filter i.e. NOT Fram). An oil’s color is generally of no indication to its remaining life. I personally think a lot of Amsoil's claims are a marketing ploy and not necessarily fact-driven. Their oil filters are decent, but the OEM Mitsu or a Wix are a better choice (reputable Amsoil dealers agree to this).

Shane, Shell Rotella-T is a great conventional oil; as is Mobil's Delco line.

Thank god someone can agree with me that Fram makes a shit filter. Napa Gold ftw!

[Kracka]

Thank god someone can agree with me that Fram makes a shit filter. Napa Gold ftw!

Fram (made by Allied Signal which is owned by Honeywell) makes a terrible product. Their oil filters, air filters, etc. are all junk. You are MUCH better off with the SuperTech oil filters that WalMart sells for $2.

Napa Gold is a Wix filter btw, incase anyone was wondering.

Pennzoil Platinum synthetic is being regarded by many over on BITOG as being right up at the top as far as off the shelf synthetics go also. People are often rating it higher than the US Castrol Syn.
