Engine Oil

[commodorev6]

Hi,
Just wondering if anyone knows if the Nulon 20w 50 semi synthetic engine oil is still available. Finding it difficult to find at the large auto stores.
My alternative is to use either a premium mineral 20w 50 by Nulon or the 20w 60 by Penrite. No semi-synthetics seem to exist apart from the one made by Nulon?
Thanks

I'd imagine the market is pretty small these days for a semi, haven't seen it in ages. How many kilometres? Personally I'd be moving to a fully synthetic

Plenty of semis out there but probably not in a 20w. 10w there a few options. Can't remember if 15w comes in semi or not.

I use Penrite 15w-60 fully synthetic and my engine loves it.
It's says that it can be used in place of sae 20w-50.

The car does less than 1000km a year and its a yearly maintenance engine oil and filter change.
