Today's ink is Robert Oster Motor Oil. This ink came out in the last few months, and it immediately reminded me of Robert Oster Melon Tea, which I love, so I knew I needed to give it a try. I purchased my bottle of ink from Pen Chalet.
Motor Oil is a dark brown with black sheen.
In large swabs on Tomoe River paper, all you really see is black sheen and dark shading.
Dry time: 40 seconds
Water resistance: Low
Show through: Medium
On Step Forward 21 lb copy paper from Staples, the ink behaved great-no problems.
I used a Pelikan M605 White Transparent with a medium nib on Tomoe River paper. The ink felt nice and smooth, a little bit on the wet side, but no flow issues.
Overall, this feels like a darker version Robert Oster Melon Tea, which I think I prefer over Motor Oil. It behaves well, and has a nice flow, I just prefer Melon Tea.
