So what you meant to say, actually, is that Carl liked a number of products, two of which were Shell and Penrite.

*sigh*

As usual, your initial post was ambiguous and misleading.

Thanks for finally manning up with the clarification.

Like I said, well done on the change to Penrite. You should have taken Carl's advice about it years ago. You know how he researches his stuff!!

Shell and Penrite are brands, not products.

Castrol products are also perfectly suitable if choosing the right one.
