I am back from my vacation and read this thread again and some bits and peaces at the Synlube Homepage.
To make a long story short, I stay sceptic...
I still think that the claims from Synlube to exceed ACEA, ILSAC, API etc Specs with one oil without having passed those tests is at least questionable.
In some countries of this world this way of doing marketing could be even a fraud.
Being a skeptic is a good starting point for investigation if it doesn't mean rejecting information without justification.
I quoted this statement of yours, because I am still waiting for valuable information. It is common practice in the industry to use industry wide accepted tests to compare oils and evaluate them. But obviously these results do not exist for Synlube products.
SynLube is a "lyophilic sol". The colloid ions in SynLube are permanently attracted to the ions in the liquid
lubricants. They will never settle. They will never clog the oil filter or passages.
To verify such a statement, you should have at least results from a cold sludge test from Sequence VE/VG test, a M111 ACEA sludge test and a Peugeot TU3M hot oxidation test. So tell me, as Synlube does not have these results, how can they make such a claim?
If I understood this right, you want to use this oil with "refreshing" for 10 years and 105k miles.
At Synlube I found this statement:
But likewise these permissible extended oil change intervals are based on the expected service life of ONLY 5 years or 50,000 miles for vehicles operated under ideal conditions. If vehicle is operated under severe service operating conditions (as most vehicles are), or if longer service life is required, this extended service interval needs be likewise reduced to one half or one third.
This means that engine oil should still be changed every 12,000 to 7,500 miles in most automotive and light truck applications.
As Synlube states that most vehicles need an oil change after 7,500 - 12,000 miles - what makes you so sure that you are using the right driving pattern?
