I've been to the Auto-rx website several times, but where can I get more info. on Neutra and Lube Control? Who makes them? Where to order? How do they differ from Auto-rx in chemical composition and mode of action?
Dr. T, there's a bounty of information right here in the additives section. Try limiting your searches to threads with contributions by Terry or MolaKule, as they've spoken of makeup and the effects several times.
On the label of the 1 gallon bottle of 131 Neutra, it reccommends 1oz added per quart of oil capacity for the last 300-500mi before an oil change if used as an engine flush. Guess I'd go about the same ratio and time if doing a tranny flush.
