I have some NEO 0W-5 (di-ester) engine oil left over from my racing days, along with some 7wt gear oil.
It seems to have darkened up some, even though it has always been kept in the dark, but still has a wonderful non-dino oil aroma.
This stuff would be getting close to 10 years old now, and as a cosequence, I haven't been game to use it.
Actually, it's the viscocity that scares me more than anything.
Would it still be OK ?
Would it be safe/worthwhile to use 200ml-500ml as a cleaner/solvent (remember, the base is 100% ester) in a 10.5 litre diesel sump ?
It would be such a waste to dispose of it, but what on earth would I use it in here in Australia ?
At least I could use the 10W-30 to top up my 351 Clevland that used M1 15W-50
