I love motor oil if it is a slow bite throw Motoroil there is a big difference between manufacturers.
Motoroil is not a hard and fast color. I have like 5 different ones. I like the std 148 it has the stongest green tint. Also like to add a drop of amber or Tiger Gold for every drop of motor oil (just what I like) Tried to add green hi-lights but did really care for the effect. But I do add a smidge of .008 green glitter helps highlight the green. Zoom has a really cool motoroil but have not been able to get close to the one they use for lizards.
In process of testing bleeding right now with chartuse tails. Mixed up several different batchs about a month ago. Seems if you put a lot of worm oil in bag they tend to bleed, the ones I left dry have not
bled so far. I put them dry in a plastic coffee can so far they still look good.
