Quote: I presume the VR means it's a 'Valvoline Racing' oil? No it doesn't have VR-1 on the bottle. It also doesn't have SM or SN on the bottles. It's been a couple years since I bought this case. I'll be needing some more sorta soon.
Yes, the VR-1 in the silver bottle is badged as "Racing Oil". It is a conventional oil with a street detergent package. The black bottle of VR-1 racing oil is a synthetic. There is another black bottle of VR-1 which is badged as "Not street Legal" This one does not have the street detergent package. It is made for users who are going to change oil frequently, like after a race weekend.
If you were to go to the store and buy the regular Valvoline oil that you have in your two year old case, it will now be the newer SM or SN formula that you do not want.
