    Default 2015 STL Oil consuption sanity check

    During a 4400 mile ride through the north central plains, my wife's ST went through 1-1/4 quarts of oil. (We were using Amsoil synthetic 10W40). Other posts in this forum say many times that 998 oil consumption is the nature of the beast, but is this excessive for lots of highway riding? Now that we're back, going to change the oil to XPS blend to see if that makes a diff.

    Just wanted to check.

    I will use more oil if the temp is 85 degrees of higher. The most i have used between oil changes is a quart. I ride double 80% of the time. Bruce

    Running a lot at high RPM will use more oil. Also, overfilling will tend to cause more oil to be used. Are you checking the oil level correctly? If not, this may be a big contributor to the high oil usage.

    Depending on how many miles you have on the motor, this can also be a contributor. As the engine breaks in, oil usage will usually go down.

    Pretty normal usage, I just did 4,800 miles in 10 days and burned just over a quart.

    I use about a quart between oil changes (4600 miles) but I have noticed now that I'm up around 20K miles it uses a lot less. I've ridden 1200 miles on the last oil change and haven't added a drop.

    Yes, I'm pretty diligent about checking the oil on a warm engine, letting it idle first. I fill to the max mark or a little less

    Interesting comment, because we were riding pretty much the entire trip at 90 to 100F

    Default Just to add another engine.

    I find that if I (or we 2 up) ride around 4K or less RPM, my oil consumption is marginal. But if I start exceeding that, regardless of gear, meaning freeway or running harder through the gears, I will burn about 6 oz in about 400 miles. This concerned me for a while, but after reading the forums on this subject I calmed down.

    Many people will check their oil at the beginning of a ride after letting the Spyder idle for awhile. This is not only hard on the engine, but will not necessarily give you an accurate oil level reading.

    Idling will get your coolant temperature to operational levels. But your oil will still be cold. What you want to do is check your oil after riding several miles to get the oil up to operating temperature. Many people check their oil at the end of a ride. This works very well as you get an accurate reading. And you know you're good for the next ride.

    That is my method of checking the oil. If I ride 20 miles or 300 miles once I pull into the shop and check the oil and like you stated ready for the next ride just get on her and go. Of course after a visual walk around.

    1 1/4 quarts of oil in about 4400 miles?
    That sounds just about right for the 998s!
