Some information which should prove useful: I used to run my GS paralever on Unipart 20-50. This was available some time even after the demise of the business. I then switched to Comma Motorway 20-50. Then this disappeared from shelves! Searching around, I came across another Comma 20-50. Here it is at a bargain price ... https://www.ebay.co.uk/itm/2-X-Comm...747326&hash=item23c8184957:g:SY4AAOSwTuJYob57
Unfortunately there was no info available re its SAE rating! So, I contacted Comma technical help and got this initial reply:
The X-Flow type MOT 20W-50 meets the requirements for SAE 20W-50 and contains a good level of additives. However, this product has not undergone the commercial investment in engine testing to validate a specific level of performance like API or ACEA specifications and others a basic protection.
Hmmmmmmm! I mulled this over and then it occurred that this might simply be a marketing issue? i.e. the product was new in terms of its market presence but maybe an "old" oil? So I asked them! I got the following reply this morning ...
Dear Peter,
My apologies for the delay in our response.
Yes, Comma Motorway is the same oil as X-Flow Type MOT 20W-50.
Please let me know if you have any further queries or issues.
Best regards,
Ta daaaaaaaah!
