How to unlock the Grease Monkey achievement in Rocket League - Definitive Guide
• Decals
• Paint
• Wheels
• Rocket Trail
• Topper
• Antenna
• Trail (Just press on the only available one [as of July update])
There is at least one item unlocked for each category from the off when using the Octane body so this can be unlocked straight away. You do not need to change all 4 paint colours but I did in my video to be sure.
Press on the new items to apply them for the achievement.
Here's a quick video (missing the trail though)
Here I have a video guide for the grease monkey achievement just incase you are unsure how to get the achievement or want to check that you are doing the achievement right.

Then from the main menu go into 'garage' and customize each of the following slots to unlock the trophy making sure to use the body called 'octane'.
Decal

From the Main Menu, select "Garage." You must customize each slot of your vehicle to unlock this achievement. This includes Body, Decal, Paint, Wheels, Rocket Trail, Topper, and Antenna.
From the main menu, select Garage. Here, you can customise your Cars with several categories of items such as decals, paint jobs rims, flags and toppers but for this trophy you just need to customize a Decal, Topper, Rocket Boost and Wheel.
You should have access to all of these after a couple of online games through the New Driver Challenges and levelling the Free Rocket Pass a little. Once you have the items required, just switch to each of them for this trophy.
Once you have one of each item unlocked, navigate to the garage and apply one item of each category to your Car. The trophy will unlock as soon as you do.
