Changes XL-7500 Formula To Enhance Oils, Stay Competitive
Vice President of Manufacturing Alan Amatuzio discusses changes in the
AMSOIL XL-7500 Series Motor Oils.
will be using a different formula for its XL-7500 Motor Oils. Why did
AMSOIL change the formula?
XL-7500 oils are the oils of choice in the retail oil change market, and
primarily because of warranty concerns the customers in this market
require API-certified oils. In order to obtain API SL/ILSAC GF-3 certification
and still remain cost-competitive with the other oils sold at retail oil
change outlets, we had to change to Group III basestocks. To obtain API
certification with our top tier basestocks would have priced our Dealers
out of the market.
Group III basestocks synthetic?
they are synthetic. Group III base oils are highly processed oils and were
classified as synthetic in 1999. That year, the National Advertising
Division (NAD) of the Council of Better Business Bureaus ruled in a
complaint by Mobil Oil Corp. against Castrol North America Inc. Castrol
claimed its product, Syntec, was a synthetic oil even though it had used
base oils since 1997. The ruling by NAD said Castrol presented evidence
that constitutes a reasonable basis for the claim that Syntec, a Group III
based formulation, is synthetic motor oil.
did that change impact the lubricant industry?
the decision by NAD shocked the lubricant industry. However, many studies
show that Synthetic Group III base oils have been completely changed and
converted and are significantly different from traditional Group I mineral
oils. They have come to be recognized in the industry and by consumers as
all Group III oils equal?
as a matter of fact, they are not. One of the big problems with Group III
base oils is the lack of consistency from one manufacturer to another.
While the physical properties may meet performance parameters, the
performance characteristics can vary widely. Thatís because of
differences in the crude oil and the different processes used to refine
the crude into Group III
basestocks. Itís quite different from PAO production where the
properties and performance are fairly consistent between manufacturers.
(See Table 1.)
did AMSOIL resolve these differences in performance characteristics in the
Group III basestocks?
has selected the best quality Group III base oils and spiked them with
oxidation inhibitors and TBN. They have more gusto than other Group III
oils and are fully
for 7,500-mile drain intervals. (See Chart 1.)
prompted the new GF-3 designation?
new designation was driven by three key performance requirements: improved
fuel economy, improved protection of emissions control systems and the
need for more robust engine oils that offer extended drain intervals.
These GF-3 oils are greatly improved in terms of oxidation stability, high
temperature deposit control, fuel economy improvement and retention of
fuel economy benefits, and lower oil volatility and oil consumption.
does the new formulation mean for AMSOIL Dealers?
new formulation allows Dealers and customers to save money. Effective July
1, the XL-7500 5W-20, 5W-30 and 10W-30 motor oils cost 20 cents per quart
less for all programs.
the other AMSOIL motor oils impacted in any way?
other motor oils remain unchanged. They are the very best quality
synthetic motor oils, formulated for 25,000-mile, or one-year, drain
intervals. Our main line motor oils are the premier, top quality oils on
the market and that is where they will stay. Unlike the
that considers Synthetic Group III a major step up in performance, our PAO-based
motor oils are still the best.
are basestocks defined and classified?
American Petroleum Institute classes basestocks in five Groups, defined by
sulfur content, saturates and viscosity index. Groups I and II are
petroleum-based oils. Group III, as mentioned before, have been most
recently designated synthetic. Group IV
basestocks are PAO chemistry. Group V represents all stocks not included
in Groups I-IV, such as esters, silicones and polyglycols.
did AMSOIL choose to use Group III basestocks in these particular oils?
AMSOIL XL-7500 oils are particularly appropriate for Group III basestocks
because they are stable and resist oxidation and volatility. They are
recommended for only 7,500-mile, or six-month, drain intervals. Primarily
sold to the installed retail market, they give the retailer and customers
what they want and need for their vehicles.
