I gave Red-Line a call today, mainly to verify that the maintnce dose level for adding SL-1 fuel system cleaner ( amount per U.S. gallon of gasoline ) is still the same. I mentioned to Dave that the label on the SL-1 bottle use to say the recommended maintnce dose was 4.45 mL per U.S. gallon. And I asked him if a dose of approximately 4.5 mL per gallon is still a good recommended maintnce dose. And he said yes. He said the product is the same, just the label has been changed over the years.

BTW, I actually do keep a plastic translucent white 100 mL graduated cylinder I got from McMaster-Carr in my vehicle with a bottle of Red-Line SL-1 and use the trip B to record the miles since last fill, divide by MPG = number of gallons use since last fill. Multiply that by 4.5 = how many mL of SL-1 to add before the fill up.
Store the graduated cylinder upside down in several used plastic grocery bags, and discard the bag next to it each fill up because the residue of the SL-1 actually pulls moisture out of the air and mixes with it and makes a mess of the bag.
Also wear glove or use old plastic grocery bags as gloves, this stuff is a oil that gets on anything you touch if you do not wear gloves or wash your hands if you do not wear gloves.

Then I asked him for NOAC numbers on there oil so I could post them on bobistheoilguy. The following is the data he sent me today:
James,
It was good to talk to you today, I have listed the NOACK evaporation numbers for some of our oils, we consider this an important characteristic and typically lower than others.
NOACK evaporation loss, 1hr @ 482°F (250°C) %
0W20 - 9
5W20 - 8
5W30 - 6
Regards,
Dave Granquist
