Changing 2 stoke outboard oil from Quicksiler Premium plus to Quicksilver DFI? is this safe???
Hi all
Just after some advice please. Ive always used Quicksilver Premium Plus in my Optimax 115 2 stroke. When I recently had it serviced, I was told by the mechanic that I should be using Quicksilver DFI in it. I bought a couple of bottles and have now run out of the Premium Plus, but am pretty hesitant to start running the DFI in it. I obviously asked the mechanic if changing it over would be OK, and he seemed pretty positive it wouldnt, but also a bit non-commital about it...
Can anyone tell me if changing the oil types (they both seem very similar, both ae the same brand, both and TC-W3 and if I am correct, both are synthetic?) will do any damage?
What is the actual difference between the two oils? (besides the colour- the Premium is green and the DFI is bronze).
Will changing over have any bad effect on the motor?
Ive mixed a bit of each of the oils in a container and let them sit for a couple of hours= there doesnt seem to be any seperation/ gelling, but Im still unsure...
Any help would be greatly appreciated- Ive very paranoid about this and just dont want to make an expensive mistake. Ive got a big trip planned on friday and dont want things to go wrong!
Thanks as always!

I'm no expert but I wouldn't
I'm no expert but I wouldn't expect there would be any difference if both comply with recommeded oil (particularly given there both the same type) Any two stroke oil would obviously be better than running with no oil. - I've occasionaly topped up my oil tank using a different brand due to being in remote locations with no probs. (running a older 1993 70hp Johnson though).
Hope that is of some help

As a rule i say not to mix
As a rule i say not to mix oils from time to time but i would just run yours down a little and then add the new DFI oil. No issue really. Its just when people change ever time they top up it gets nasty.
