    Anyone tried penrite 15w50 premium mineral oil? Went to their website and it recommends that for a 1989 Yamaha Fzr250. Says its the same as 10w30. Didnt know what oil came with it

    penrite has zinc in it and helps bearing life. some use caltex diesel oil for same reason. should be ok.

    Caltex Delo 400 15w40 is very good, you can get it from Caltex servos in 5L and 1L bottles. Just make sure it's not delo gold, silver, or anything else.

    The 30 in 10W30 is the high temp value of the rating. It means that at the high temp this oil will have the same viscosity as a 30 weight single grade. If the engine manufacturer specifies a 10W30 then you want to have a damn good reason to move away from that especially with an engine that spins as high as these. I would strongly advise against using a 15W50. If all else fails read the manual.

    Hmm, the Penrite site suggest's 10W40 for the FZX250 Zeal?



    Photo below taken from the 3LN3 Service Manual supplement, not sure what the 3LN1 has listed


    2L for an oil change (no filter)
    2.2L for oil and filter change
    2.7L after an engine overhaul

    Manual say's

    Check engine oil
    Start and run vehicle for 2-3 minute's at idle
    Turn off engine and wait 2-3 minute's, then check oil level
    Should be between the 2 line's on the sight glass



    Referring to the figure
    use the viscosity number suitable for the outside temperature's

    I went for the thinnest oil for my FZR, was $38 on special at Supercheap Auto
    I don't think i'll ever be out riding it if it's over 50 degree's C, and it rarely get's below 0 degree's here too

Go to penrite oil and look up what they reccomend for a 1989 yamaha fzr250 and it will come up 15w50 and states its the same as 20w40 but f'd if i know lol i just chucked castrol oil in it and i think it was car oil haha but seemed to work fine n no clutch slippage
