    Size of an oil vendor and its budget on R&D

    excuse my ignorance but i would like to pose this question: how come a smaller sized (e.g. liqui moly ($675.65M turnover), motul ($368.88M turnover) etc.) engine oil vendor can produce better oils than giants like shell, mobil, castrol etc.? for instance shell spent $962M just on R&D in 2019...

    Filtron and Purflux

    i prefer mann filters. though often it is either too expensive or hard to find their products online here (talking about my vehicle. maybe it's too easy to obtain for -say- VAG). i've heard good things about filtron (mann's sub-brand) and purflux (sogefi group's) what do you guys think about...
