    @irongamer727 To each their preference. My mate works in the oil industry for motul, so when I need oil I just ask him and he'll bring the best stuff 😛

    @minia I think each to their own. No reason, I just prefer Silkolene.

        @irongamer727 As long as you stick with the bigger well-known brands you can't really mess it up. As for types of oil I use yamaha 10w-40 4t for my gearbox and motul 100% synthetic 2-stroke oil for the engine for all my 2 strokes. If I don't have motul, I just go with castrol.

        Yamaha DT125R Blue 2002, XT 125 1982, Yamaha WR250Z 1992, BMW GS650F 1994, Benelli BN302 2015

          @minia I run Castrol Power 1 2T Racing in all my machines. Cheap and hopefully good.

            Hello everybody, now I'm look at getting a Dt125 as my first bike, now I have a few questions about the oil and coolant. Gearbox oil what oil would I need how much and how often would I need to change it. Engine oil what oil would I need how much and how often do I need to top it up, and coolant is it just any coolant for a car etc how much and how often would I need to top it up. Sorry the seemingly silly questions I just want to to know the rough cost of running the bike before I get one many thanks. 🙂

            @yamahaman5000 I always found that Silkolene products were very high quality and performed very well indeed. 😉

              My castrol oil cost roughly £10 for 1l. I found that silkolene for a whopping £22!!

              You guys think there is a difference in quality between them?

                @irongamer727 You can get Silkolene comp 2 for £15 a litre, which yes is more expensive, but as with everything in life - quality does not come cheap. Some people will say that oil is oil, but all the top race teams will most definitely not be using Castrol oil for-sure.

                    @irongamer727 Silkolene 75W-90, is what I have just put in my Starlet. Think it was around £75 for 4 litres.

                        @irongamer727 Castrol GTX Semi Synthetic lol.

                        I'll probably go with Silkolene for the RS, but the DT only ever got Castrol. I was on a budget at the time. And the DT doesn't make any power, plus engines were ten a penny.

                          This is good stuff then? Reasonable price as well.

                                @irongamer727 Yes, but I have had good oils mess with my clutch before. Castrol magnetec cause the clutch to slip uncontrollably

                                      @irongamer727 your being wayyy too picky with your oil just grab some for wet clutches at a good price I’ve used the cheapest oil money can buy in my 4 stroke and I liked the stuff the best cheap oil I used was Tesco’s own brand it was genuinely good oil

                                        I mean, I wouldn't put cheap stuff in, but I wouldn't overthink it either.

                                          @calum yeah but there’s really not much into it especially for a 2 stroke I’m just saying some of the best oil I’ve had was Tesco’s and that wasn’t dirt cheap but was still an ok price
