Castro GTX offering a High Zinc oil

[Yarb]

Just saw this. Maybe I’m late to the game here but this is the first I’ve seen in High Zinc additive.

I spotted a FB post the other day where someone was asking about the best oil and filer for their L-series engine. So. I did a search on any available reports or charts on zinc / ZDDP content and came across this one. The new Castrol product is certainly better than the one listed in the chart but the Lucas oils still seems to be the top conventional oil products.

There's a nice - circular, historical - link between the Castrol brand and 'our' cars too, as they were big sponsors on some of the Works rally team cars in period:

I use Kroon Classic oil here in the netherlands, they recommend 15w40 , 20w50 seems way to thick to me for a stock L24 to L28...

Lucas oil seems to have a 10w40 to I see
