I was out shopping for a 5 quart jug of Castrol Edge, WITH TITANIUM, for my next oil change, in 5W30 specification. All I could find was 1 quart bottles, for just under $10 per. Edge with Syntec is available, as is some other (older??) plain 1 qt bottle of Edge. As much as I love the stuff, I can't spend $50 bucks on oil, when there are plenty of high quality synthetics for less. I am not really into the super ultra brands like RP and Amsoil, but will note that RP was $0.40 less per quart. Any thoughts? Is this just inventory craziness with the Syntec/Edge brand realignment? Does anyone think Edge with Syntec will support 10,000 mile OCI's?
