Hey guys, my dad has a 1969 triumph t120 Bonneville that I'm working on currently. I wanted to get some advice on oils though.
For motor oil it recommends a variety that are all SAE 20 to SAE 40 such as energol SAE 20, 30, 40. For this I was looking at mobile1 4t racing 10w-40 because it has a good reputataion, 1200 ppm ZDDP, and was recommended by an oil chemist that I spoke too. I want to get some more opinions though and would like to hear if there is anything else I should look out for when getting oils for such an old bike.
For gear oil it recommends EP 90 oil from a few different brands such as castrol hypoy EP90. I haven't done any research into this yet and wanted to get opinions on what might be some good options, and what to look out for. I have found that Kroon oil carries a "classic gear EP90" in addition to a "classic monograde 30" and "vintage monograde 30". Does anyone know whether any of these are any good? In a brief search I didn't find much of anything. Is it worth getting "classic" oils for the bike? I feel like getting an appropriate modern oil should provide superior protection.
Thanks,
River
