VR-1 was changed due to LSPI in modern engines a couple of years ago. Sodium and calcium levels were altered. The changes we've seen in oil due to this and additive shortages don't seem to end.
I prefer Semi- Synthetic GP-1 by Driven, since we started testing this oil 4 years ago I see the coolest temperatures and highest oil pressures of any oil. Basically its the proven Pennsylvania crude (ARG) mixed with the additive package found in DT50 Driven oil. This came about after DA Lubes bought the rights to Brad Penn from ARG. Lots of times people just look at the anti- wear package in a given oil, and they don't consider how the detergent package comes into play within the formula. All of this constantly changes, and what I prefer today I likely won't prefer later.. You have to stay aware with VOA and UOA to note changes, because no one is going to tell you. |
