You couldn't even guess what a 3.2oz bottle of limited slip additive for my Dodge truck's differential is. I call it liquid gold myself....luckily there is a dealership close by where I can pick it up....no telling what they would charge me for shipping.
If I had a sample size bottle, I'd send it to you free, but I don't. I use the larger size so it will last me longer with less shipping. But I'll tell you what....I'll split the $5.35 shipping charge with you if you think half is more acceptable. I'll paypal you $2.68 if it will make it or break it on you getting some to try. I'm serious. Just use the email me link instead of PMing me please.....my PM box stays full most of the time and I've found myself culling out some of the important ones to make room for more. Thanks.
