Hello Lara,
.
To get answers to specific issues, the best I can suggest is use your 'search' icon.
On my telephone, the 'search' icon is in the bronze header, all the way to the right.
Type in something along the lines of 'calories in a nicely-chilled bottle of refreshing Exhaust Fluid' or 'is a hamburger better with power-steering lubricant or should I only use it on tacos', and this should show dozens of methods to fix/by-pass any of your urgent dining and hydration concerns.

As far as a written guide for your specific rig/situation, this might be your grand opportunity to gain fame and fortune...
