getting back to the sae chart https://syntheticwarehouse.net/wp-co...ositychart.jpg
for what i see, this is an official document. but i wonder why it does not state the specific sae for each product.
it was until pizzaguy brought the data that i learned there is more than 1 sae specification. thanks, pizzaguy!
and this specific number of each type should be printed at the chart,as it is crucial.
so 1 group is saej300 and the other saej306.
