Interestingly, there is a stockist less than 50 miles from me, but I don't think I'm ready to try 20w-60 yet.
LOL you've gotta love Penrite, they're pretty much a thick oil cult down here, especially for older cars. They do seem to be changing though, I've noticed recently they've added some good new thinner oils to their synthetic line up.
For comparison, Valvoline, Shell and Castrol's Australian sites recommend 10W40 or 15W40 for your 4-Runner.
