Blake's Diesel Care LLCLogo Design Contest

We do all kinds of diesel repair, maintenance, and performance for light duty and medium duty trucks (No semi trucks!).

Blue- favorites are a navy/dark blue, yellow, a splash of red, black, grey, white.

We have a simple business card (attached picture), which is catchy and easy. We have a decal, which I will attach an image of, that we do not like at all. It is boring and does not stand out. I do like the colors, but somehow think that a bit of red in it would create some spark. We also are thinking that we do not want to include the "Care" in the name on our design. It is too long of a name to read quickly and easily. We don't intend to continue to do cummins conversions so please don't include that either. The phone number would be really good to have in it, although I'm not quite sure how the works with an actual logo.
I've imagined an injector faded into the background (I'll include a picture of the type of injector that I'm thinking of), but the only reason is because I want it to be connected with what we do and our competitive diesel shops typically use turbos in their design, so we do not want to copy.
We would like to be able to use the design on sponsored trucks for truck pulls as either a vehicle wrap or as back window lettering and on bumper sticker/window sticker type decals for customers trucks.
A few other ideas I've imagined are a triangular shape with our name and then a yellow banner in the background, angled lettering with double yellow lines as on a road underneath the lettering, or just a catchy design with no background to the image as in the one we have.
We've tried to come up with ideas on our own and I'm so stuck! My creativity is sadly lacking so I hope you can understand what I'm looking for and I'll look forward to seeing what you can come up with!
