To all:
There are a number of factors that will ultimately determine the life of the
oil used and its ability to protect your engine, & Powertrain. The base
oil (
synthetic or mineral) is the most criticle factor....and the the addatives or packages (polymers used to stabilize acidity and oxidation) included in the finished product...Oh! and don't forget the filter...
1. Why add
oil "boosters" to assist in what normally takes place in any oil...(STP,Prolong, slick 50, and the likes.....) especially in a mineral based oil which begin to loose viscosity after 600 or so miles......I tested 12 brands myself and included 4 popular synthetics as well.... and they all are different..
Reason denotes " If a tables legs are weak(meaning baseoil) why add more weight on top of the table...." I say invest in a much stronger table"..... Right! In this case a 100%
synthetic oil Brand (
AMSOIL).
2 . The Type 4 and type 5
synthetic oils are Organic and 100% synthetic... however there are performance differences between them to dictate their practicle applications...especially in the automotive industry.
Type 4 lubes "polyalphaolephins" are the most robust (Stablity and longest service life 36,00 miles of more or up to 3 yrs) over their type 5 lube counterparts "Di-Esters" (short stabiltiy 60-90 days, and high stress) are commonly recommended in Off Road Racing. Never put a race-oil in a street car for which the internal oil pump was never specified or designed to handle...
3. There are very few only 2 lubricant manufactures who's specs meet and US DOD and Mil specs for extended and severe service; especially in their New M1 Abrams tank and X18 & Yf22 Jet aircafts (Mobil and
AMSOIL)
4. Because the filter is the only device for cleaning the oil and removing sediments which flow in the oil You would need the most efficient filter to compliment your lubrication system. When the typical OEM and Aftermarket filter contain a paper element, (Ford Motorcraft, Fram, many others) and is only efficient up to 76% for again 600 or so ...miles yes your oil would become black and evenually loose itsability to properly lubricate the parts with .002-.005' tolerances......Get the most efficientfilter out there available to protect and keep the oil as clean and as long as possible.... even up to 25K miles...They do exist and I have seen a few filtering systems designed specifically for extended use... A 98.7% efficient @ 15microns Full Flow Filter which even surpasses Mill specs....
AMSOIL AAo(New Product line).
5. There can only be One! and its AMSOIL, since 1972 World Leader in Synthetics and holder of the Most Lubricants Patents (API and SAE) and this new Filter Technology standard...
Remember "A chain is as strong as its weakest link"
Why Would you use any products or put anything less than the best in your Vehicle or equipment....?
Hope this response was helpful.......
