Customer Questions & Answers

  • Question: Are the oils suitable for all motorcycle brands?

    Answer: Yes, they are recommended for all major OEM brands.
  • Question: Do the oils protect against extreme temperatures?

    Answer: Yes, they protect against extreme temperatures and fuel dilution.
  • Question: Are the oils corrosive to internal engine parts?

    Answer: No, additives in the oils prevent corrosion of internal engine parts.
  • Question: Why do they show 5w-40 on pic and you get 20w-40?

    Answer: I didn't know they made a 20w-40; I couldn't find it on the Quicksilver website, either. I do use the 20w-50 V-Twin oil in my Harley and like it very much. Without knowing what your end us is it's hard to make a suggestion.
  • Question: Does this have molybdenum?

    Answer: Yes, Full Synthetic Quicksilver has Molybdenum.
  • Question: Will this work with a 2000 Electra glide?

    Answer: Quick Silver is a division of Mercury Marine. I have been using it on My last 4 Harleys. Wide Glide Softtail, Screamin Eagle Ultra Classic, Road King & Street Glide. I also use it in my 200 Suzuki outboard, & Power Stroke diesel Great oil if U can find it at a fair price.
  • Question: The price increase on this is bad. was selling for $26 months ago. it is synthetic!! not crude?

    Answer: All synthetic products are from crude base stock refined to the purest finished product and the quality allows it to be called a synthetic oil by the authority of the US Government.
  • Question: Is it ok if I use this oil for my brand new Dual sport dirt bike for break in? it's an X-Pro Enduro Hawk 250cc

    Answer: It's full synthetic motorcycle oil. So yes, it's fine to use for break in or at any stage. I used this oil as a substitute for my normal brand when it became unavailable... My trike had over 60k miles, and it worked great! Good quality product without the ridiculously high price!
  • Question: Will this work in my 04 Suzuki Eiger 400 auto

    Answer: Yes but at it’s current price you can get a complete synthetic oil change (4qts AND a filter) for the same price if you do a bit of googling.
  • Question: Will this work in a 2007 yamaha rhino 660 cc ?

    Answer: Yes, it should
  • Question: Is the API ratings listed anywhere?

    Answer: No, it’s synthetic motor oil only
