Abstract: New, highly effective detergent/dispersants for use in spark ignition fuels are described. They are Mannich condensation products formed from (i) one mole part of at least one substituted hydroxyaromatic compound having on the ring both (a) an aliphatic hydrocarbyl substituent derived from a polyolefin having a number average molecular weight in the range of about 500 to about 3000, and (b) a C.sub.1-4 alkyl; (ii) from 0.8 to 1.5 mole part(s) of aliphatic polyamine having one and only one primary or secondary amino group in the molecule capable of participating in the Mannich condensation reaction; and (iii) from 0.8 to 1.3 mole part(s) of aldehyde, provided that the mole ratio of aldehyde to amine is 1.2:1 or less. Carrier fluids such as poly(oxyalkylene) compounds further enhance the effectiveness of these Mannich condensation products in minimizing or reducing intake valve deposits and/or intake valve sticking.

Abstract: An automotive roll-up tool kit. The tool kit is of flexible plastic and has a plurality of compartments or open top pockets receiving the tools and increasing in size from one end of the kit to the other. The front of the compartment is constructed of transparent plastic for further identification of the tool with the top flap closed. A top turn over flap ensures that the tools do not fall out and is marked with registering names of the tools. A trouble-shooting instruction manual is inserted in one of the pockets. A tab at one end is provided with Velcro pads adapted to stick to mating Velcro pads on the back of the tool kit when the tool kit is rolled up.
