For quite some time I have been planning to make a Guinea Pig of myself and be the first to try Auto-RX through a Canadian winter.
Auto-RX comes out thick and a tad chunky especially if the bottle doesn't sit in hot water for a while before adding. Frank said it does not affect the pour point of the host oil. I was skeptical: Why would he have occasion to test this assertion at colder than -25? Or test this assertion with any 0W30, let alone GC?
The short answer is, pour point after about 5 months and 4900 KM (3000 to 3100 miles) was -36 C.
Another testiment to Frank and Auto-RX!
The long answer lies in this posting, a tale of a FOUR-samples for UOA's, to 2 different labs, with Terry Dyson's interpretation.
Yes, this could be a long one, but actually that's what I hope. This is for the benefit of those wondering the difference between WearCheck Canada and Toromont.
The car is a '96 Pontiac but the engine is from an "'01 or '02 Buick LeSabre...installed with under 20,000 km on it, that was about 5,000 km ago" I was told by the dealership when I was about to buy it late in August of '03. Sorry, Patman and all others, that means I can't quite put all the info into the subject line that I would like.
When I had my by-pass filter installed in April, the oil was drained, and I specified and double-checked that neither the first nor last litre be collected, and the remainder was collected. Being a horrible procrastinator (SORRY) that jug sat about 2 months. I then poured it into 2 sample bottles; one went to Toromont and one went to WearCheck.
The other 2 samples sent in to each of these will be covered seperately.
Here are the results from the samples from that jug. The WearCheck one was interpreted by Terry Dyson...
