Performance Lub is a small online site which sells some of the harder to get and more expensive lubricants + spark plugs

Brands are like Royal Purple, Redline, and some more standard stuff.

The prices are very good if you search around and the guy who runs it Harold is great to deal with.

Sometimes it's a bit of a hit and miss with sites you don't know about, but this one is a hit! Just posting up because I had a good experience and am a pretty cautious online buyer.... and have a bit of spare time on my hands!
