Sealant questions. Mavis n Stans.

I have some Mavic xa wheels. Ust rims n tyres. Supplied with Mavic sealant.

The Mavic sealant is £9 / 120ml. Stans is £22 / 950ml.
Obviously I would prefer the cheaper Stans. Can I mix them?

Mavic says 120ml per tyre (for my size). That is going to work out very expensive over the years with top ups.
I have only done my back wheel (for pinch flats), used 60ml / 2oz.
I understand that less sealant means a slower puncture repair. Are there any other issues with using less?

I tried filling the tyre up through the valve (valve removed), almost impossible, took ages, so I cracked the tyre and poured it in. Is using the valve method normally very slow?

Will I have any issues using ust rims, sealant and NON ust tyres? Ust tyre choice is limited.

Thanks for any replies.

    use a syringe to inject throught the valve. some sealant can mix well other not so well.

    Pinch flats? if you are using tubes throw them away and go tubeless. non ust/tubeless MTB tyres normally go tubeless easily. they need a folding bead though. rigid tyres and tubeless normally don't mix. -wheel building and other stuff.

    My spare tyre is wired and heavy so will get another folder.

    The sealant came free with the wheelset. But once it is used, I won't get anymore. Crazy price. £9 per tyre plus top-ups.
  • Decathlon do a good sealant, I think it's approx £8 for 500ml out there about.
    I have wired tyres on my cx bike I use for commuting, they went tubeless with the valve cores in and a track pump, I wish they were all that easy!

    Suspect spell check corrected it, can be a pain in the butt at times. Have a look on cycleclinics website for alternative sealants, he does a few different one's.
    Too many bikes according to Mrs O.

    Mavic has been changed to Mavis.

    Might be funny to some but it shouldn't be tampered with.

    Funny you think it’s been tampered will be the spell check.
