Mikey, my hubby, states that if casey were to have poured gas mixed with oil into her car it would affect the engine and make it break down. He also told me his guy stuff...that he doesn't mix it in the can but just adds the oil after he puts the gas in so in case he needs to use the gas on something else that doesn't require the oil he can (like the weedwacker)... just a little gas~class LOL.
If you were using gas with the oil to burn something, tho, it would have the same effect....added oil or not.. but.. if they find that some of the stain in the trunk is gas...they can test it to see if oil was added or not and confirm with grandpa...if that be the case. But seriously, at this point, I don't think any of that family wants to help this investigation in any way, shape, or form imhoo.
Also, I left the nancy grace show a comment form about what the earlier poster said....about gma diverting the tips to her own personal cell phone by putting out different phone numbers for people to call. Also left the bit about the gas burglary. Hopefully her people read the comments. We shall see.... (and of course I plugged websleuths LOL)
