Maybe not, but I don't use VX oil, plugs, filters, .....
but if you have a Trade Club card & have access to a participating dealer, you'd be mad not to.
I've both of those, but it still isn't worth it to me. The prices often quoted here are no different to, or more expensive than decent branded stuff from local factors. I can buy NGK plugs for about £1.90 each, and every time I've used anything else over the last 25 years I've regretted it. The oil is a good price, but I don't want to buy 3 years worth at a time just to have VX branded containers. That would still be the case if I couldn't get either 10w40 or 5w30 out of the drum at work. Plus the 3 local TC dealers are a gallon of petrol and an hour's round trip away. Which simply isn't worth the hassle for ordinary service parts.
Now if you'd mentioned things like Elite rear shocks, then I'm with you, I'd be mad not to use TC.
