For the last few years I've been purchasing 5L bottles of motor oil. This year with the new ACEA specifications the motor oil that I've been using has been reformulated to A7/B7 and dropping a spec that was applicable to me.
Anyway I can still get the spec I need from European blenders, but it only comes in 20L.
20L is no issue, it's about 3 years worth. But my issue is how to measure the right amount.
I've thought about keeping an oil 5L bottle and using that. But there is the contamination from the another blend. I could add a 100mls and shake it and rinse it out twice.
Another option was HDPE 5L water bottles which I empty and dry out over weeks.
The other option is try to pour from a 20l bottle, which I don't really want as I risk overfilling.
I also don't like the idea of a oil pump, thats just more expense and crap I don't need.
Which got me thinking, is there something I'm missing. How do people do this.
