Mixing oil

[SAFC99]

I need to top up my oil but dont know what type of oil is in already, does it matter if i put different oil in ie synthetic into mineral or vice versa or a different grade. Cheers for any advice!

Should not matter, i think most oil does mix wether it be synthetic or mineral. Probably best the next time you change the oil to know exactly what you have in. This friday mine is having its blood drained, i always use Amsoil Synthetic 5w-30

It's a lon g held myth that you shouldn't mix oils - grade of oil and particularly synth and non-synth.

As Oilman has finally put to rest, thsi is not the case at all and you can mix oils. Do a search for posts by Oilman for as much detail as you could ever want

To be honest with you I'd just drain it and do a filter change while you're there. Won't cost too much and you know it's good!

 

Won't do harm mixing but if you change it then you know everything is spot on!
