The oil analysis section deals with the problems of submitting SynLube samples to labs that are not equipped to evaluate SynLube properly. Other lubricants, for example, do not have solids and therefore the lab will flag these solids as contaminants. The main point of the section, as you have probably noted, is to provide those interested in how SynLube is doing in their engines with information that will place results from places like Blackstone in proper perspective.
With regard to cost, SynLube is less expensive. As you may remember, I projected that my total lube costs over the course of SynLube's service life (in my case) would be about $195. I am not generally a heavy driver and keep my vehicle parked to save fuel whenever possible. Consequently, I am projecting that over the 10 year period I will only accumulate 105K miles. Therefore I'll use the 10 year cycle.
Over that 10 year period, Amsoil would have to be installed 10 times and they require a filter change at 6 months (unnecessary in my opinion) to keep the warranty they provide intact. My Ranger uses 5 quarts of oil and the list price is $8.35 for the Series 2000 0W30 which is the oil I'd use if SynLube were not available. Now if you're like me, I'd press for a discount and let's say I can get the price down to $7 a quart. Then there's the filters and their top line filters range from about $9.75 to $28. Let's settle on $10 per filter. That's $55 for each year and that's only if you install it yourself. At the end of 10 years, your costs will be $550 (plus shipping and/or applicable taxes) vs. $195 for SynLube. That's a decent monetary savings of $355 plus the savings in time and the almost complete elimination of waste oil which should not be overlooked. Finally, you can return the oil to SynLube at the end of the oil's service life for a credit towards the purchase of new SynLube.
