Portent 0 Posted November 2, 2012 I will be changing the oil next month. I already have some Fuchs 10w50 but mistakenly ordered some additional Fuchs 15w50. Would this be ok to use and mix or should I return the 15w50 and swap it for the same 10w50? Quote Share this post Link to post Share on other sites
OllieVR6 0 Posted November 2, 2012 I'm no pro but I think you need to keep it the same. For the C I only use the same stuff (grade and manufacturer). In the daily hack I keep the grade the same but top it up with any oil (halfords, Renault, Castrol etc) that I have handy or that's on offer. Quote Share this post Link to post Share on other sites

Portent 0 Posted November 2, 2012 Thanks. Opie are fine to swap it and I'm in no rush so I will check the cost of return postage and if its high then I wont bother. Quote Share this post Link to post Share on other sites
Portent 0 Posted November 2, 2012 I just popped down the post office and it's £15 to post it back or £24 with enough insurance to cover it. Might try an independent courier but at that price I think I will just use it. Can't believe how expensive the post orifice is now. Quote Share this post Link to post Share on other sites
