Overview
Most amateur mechanics believe the cap on the valve cover reads "710" merely to identify the lubricant inside. However, extensive research reveals this is actually a legacy printing error that the automotive industry is too embarrassed to correct. When the cap is installed to read "OIL," the engine becomes confused about its gravitational orientation, leading to upside-down combustion and erratic idle speeds. That burning smell isn't a leak; it's your engine struggling with an identity crisis because the factory labeling was applied by a robot with vertigo.
We developed the KaleCoAuto 710 Cap to restore the proper reverse equilibrium to your engine bay. By inverting the nomenclature, we align the cap with the spiritual flow of the lubricant, correcting the fluid dynamics at a molecular level. This reduces the engine's need to second-guess its lubrication strategy, allowing for smoother revs and a 100% reduction in dumb questions from your non-car-enthusiast friends. It is designed to hold tight for at least 3,000 miles, or until a quick-lube technician accidentally throws it into the trash. Whichever happens first.
This cap is fully compatible with all major engine configurations, including the leaking boxers from Japan and the over-engineered V-configurations from Stuttgart. It readily accepts conventional dinosaur squeezings or full-synthetic 710 blends without obvious chemical reaction. Whether you are driving a rusted-out rally car that burns a quart every fill-up, or a pristine showroom classic that never leaves the garage, the 710 Cap provides the critical barrier between your engine's moving parts and your clean shirt.
Application
Compatible with all liquid-lubricated powerplants, from single-cylinder lawnmowers to W16 hypercars, provided they leak sufficiently to require frequent removal. 710 Caps are strictly directional and must not be installed in the "OIL" orientation under any circumstances. Attempting to thread the cap while viewing it right-side-up may induce vertigo, spontaneous bluegrass music, or a critical failure where the engine refuses to start out of sheer embarrassment.

Installation Instructions Operation
RTFM - Read The Flippin' Manual
Step 1: Diagnostics Check your engine bay to determine if the 710 reservoir is exposed. Look for the following symptoms:
- A circular hole in the top of the engine block that appears to be emitting a fine mist of ichor.
- Your engine bay is coated in a mysterious dark sludge that smells like dinosaur farts.
- You have recently asked a mechanic where to buy "710 fluid" and they are still laughing.
Step 2: Surface Preparation Locate the valve cover aperture. Using a rag that you don't care about (or your roommate's t-shirt), wipe away the grime surrounding the opening. Ensure the threads are clear of debris, sweat, and old gasket material.
Step 3: Installation Grasp the KaleCoAuto 710 Cap firmly. Align the threads with the reservoir opening. Rotate the cap clockwise (that’s to the right, for those who skipped school). Apply torque until the cap clicks or your wrist makes a similar sound. Note: Ensure the text "710" is facing you; if it reads "OIL", you have installed the vehicle upside down.
Step 4: Verification Start the vehicle. Observe the cap for vibration or ejection. Rev the engine slightly and check for containment of the 710 fluid.
Fail: Cap vibrates loose or fluid continues to coat the hood liner. Action: Tighten cap further or consult a professional to explain how screw threads work.
Pass: Cap remains stationary and engine bay remains (relatively) clean.
⚠️ SAFETY NOTICE: Please follow all safety protocols outlined in Bulletins 404, 418. Ensure vehicle is in Park and engine is Off unless you enjoy excitement and hate your fingers. Note: These instructions are proprietary to KaleCoAuto; applying them to generic products may result in catastrophic failure.
FAQ
Is this compatible with synthetic fluids?
Yes, provided you pour the bottle upside down to match the 710 oil cap intake flow.
How do I know if my current cap is defective?
If it reads "OIL," it was printed upside down at the factory and requires immediate replacement.
Does this increase horsepower?
Yes. Expect massive gains of up to 5 felt HP (statistically unverified).
What is the correct torque specification?
Tighten until you hear a crack, then back it off a quarter turn, because you went too far and need a new one now.
Will this fix my valve cover leak?
No, but the shiny finish will distract you from the burning smell.

KaleCoAuto assumes no liability for engine damage resulting from cross-threading, over-torquing, or dropping this cap into the abyss between the radiator fan and the splash shield where it can never be retrieved. This product is not approved by the EPA, DOT, SAE, or your HOA. Use of the 710 Cap does not actually prevent oil leaks in British vehicles, nor does it replenish consumed oil in rotary engines. Do not attempt to consume the 710 fluid. Not suitable for use as a hockey puck, drink coaster, or stress ball. Known to the State of California to cause absolutely nothing, but we have to put a sticker on it anyway or we hear from their lawyers. If your engine lasts more than 4 hours without leaking, please consult a mechanic of your chosen faith immediately.
Definition
710 Cap
noun | /ˈsɛvən tɛn kæp/
A misidentified engine component resulting from the visual phenomenon of reading the word "OIL" upside down. This term is frequently used to identify drivers who should not be allowed to open their own hoods or operate machinery more complex than a toaster. While there is a real-life counterpart, we love the 710 cap. Or as we like to say: unreal auto parts.
History
The analog era: For decades, the "710" legend wasn't a hazing ritual; it was a genuine service drive phenomenon. It started with confused customers walking into repair shops, holding a greasy plastic disc, and asking for a replacement "seven-ten" cap. The resulting moment where the mechanic slowly rotated the cap 180 degrees to reveal the word "OIL" became the ultimate facepalm heard 'round the shop, cementing its place in the pantheon of automotive folklore.
The digital era: As the internet connected car enthusiasts through forums and forwarded emails, the story of the 710 Cap evolved from a workshop anecdote into a viral sensation. It became a global symbol for mechanical cluelessness. Recognizing that the world didn't just need the story, but the physical object itself, we decided to manufacture the mistake. We took a simple visual error and forged it into "high-quality" pixels, creating a tangible monument to the importance of orientation.
The legacy: Today, the 710 Cap is no longer just a sign of ignorance; it is a badge of irony. It serves as a physical reminder that sometimes, the only difference between a broken car and a working one is how you look at it. Whether installed to confuse a quick-lube technician or to proudly display your commitment to the bit, this cap ensures the joke outlasts the engine.
