there is cheap and nasty 20/50 mineral oil (lexicon) on ebay for 10.99 delivered. Im looking for some to run an engine in next week but want something more like 10/40 and paying £20 a bottle for something that's going to last only a short while is not sitting well with me.
Now called Pistoneeze ZDDP was quoted at 1020ppmmillers classic? dont know the price or spec, but designed for "old" type mtrs.might be good for running in.
For our old 2cv engines we recommend using a Semi Synth. and "Diesel" spec as it tends to have higher Zinc Something cheap non synth for the initial run in.
It's a mine field, Andy. Some say its OK to use additives, others say not.
Nice
If it's any consolation Dave, I let the smoke out of my bandsaw motor yesterday.
