I honestly had no idea Valvoline made the VR-1 20w50 in synthetic until tonight. I have always been using the grey bottle conventional VR-1 20w50 in my newly acquired (my dad's original) 1986 911 that just turned 50,000 miles.

I was watching some videos of the Motor Oil Geek on YouTube tonight where he was testing a bunch of Walmart synthetic oils vs VR-1 synthetic. I had no idea they even made VR-1 in synthetic. I did a search on the forum and saw some people were using it. According to their product data sheets, they look very similar in terms of ZDDP and Phosphorous levels but it seems (after reading the sheets) the cold start up flow of the synthetic is better.

Anyone now running the full synthetic VR-1 20w50 now instead of the conventional?

I was checking the oil today after getting the car back on the road after years of sitting. I did a fresh VR-1 oil change at 49,525 and when I pulled the dipstick today while hot and on level ground at just over 50,000 (probably close to the 600 mile mark on the new oil) it was as clean as when I poured it in back in May. I couldn't believe it. I know on my daily drivers, I can do a fresh oil change and then drive it a bit and the new Liqui-Moly will quickly darken once mixed and flowed through the engine. hopefully this is a testament on how clean this low mile engine is. ended up adding a few ounces of oil to bring the level back to halfway on the dipstick, which brings the oil level gauge up to about the 90% full mark. I think I read in the shop manual these can consume a quart of oil per 1000 miles as acceptable, so I guess im doing well in that sense.
