Sometimes it’s the little things about the Syncro that are annoying but necessary.
For years I have tried to achieve the simplest, cleanest and less bothersome way of topping up the engine oil via the extendable oil tube. Flexible funnels/fixed funnels/combination tube & funnel and nothing really satisfied. Flexible funnels meant holding and
shaping them to receive the oil from a container which was big or small. Fixed funnels meant nudging them against the tailgate to get a reasonable flow rate. Combination funnel/tube was simply messy and awkward. And, in all cases there was the inevitable cleaning off the oil laden devices afterwards and the space these things use in the van. Without using any of the above you are left with basically pouring oil into the tube directly from a bottle like container, therein lies the risk of missing or messing the pouring accuracy - even a gust of wind can upset the exposed flow; it has happened to me. Then one day as I was squeezing tomato sauce onto a tasty pie out of a plastic squeeze bottle I experienced a revelation!
I now use a tomato sauce squeeze bottle to input the engine oil into the oil receiving tube - no mess, no awkwardness, no clean up, no storage hassle. Simply squeeze with ease and press the clip like cap on - done!
Now, you may think this was a trivial issue to raise, long-winded and probably zany, but as I mentioned earlier sometimes it’s the little things that are annoying - in this case: no more!
