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 synthetic and does not have the same detergent package. The black bottle is intended for users who are going to change oil more frequently, like after a race weekend. I would think it's fine for our low mileage cars that we change once a year.
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 be the newer formula that you do not want.
I'd heard that even the synthetic isn't that good anymore. Which is why I bought the diesl oil. I've used both the Valvoline I mentioned above and the Shell Rotella diesl oil for the past couple/few years. Thanks for the info.
I guess it depends on which oil. With the ratings changing every year or so, it has become something of a moving target. With the Brad Penn and Z-Alt oils you are safe.
Another one that is a good suitable oil but not cheap is Mobil 1 Racing 4T which is marketed as a bike oil. This product is the exact same Mobil 1 that was their NASCAR oil back in the 90's. It's good stuff. The regular Mobil 1 car oil you buy now is the watered down ZDDP package which you don't want.
