This funnel fits BMW and VW vehicles that use a half turn style oil filler cap. We highly suggest checking your oil filler cap before ordering. Without the adapter installed the funnel fits Toyota and Lexus vehicles that use a threaded oil filler cap.
We aren't saying traditional funnels don't work, but our funnels can make for easier and cleaner oil changes for not a lot of money.
The “no funnel” approach - We've all probably been guilty of this. This is thinking you can pour a full quart of engine oil into the engine through the small hole in the valve cover from some distance above it. This is easier on some engines than others, but usually results in at least some spilled oil.
The “regular funnel” approach – Unless you can find a funnel that will friction fit into the oil fill port, they are usually too long and end up touching a baffle or something else causing restricted oil flow. Since they don't seal, if you pour oil in faster than it can drain down into the engine oil might overflow. Many times these funnels require you to hold them the entire time, otherwise they tend to fall over. Usually you can pre-open all the quarts of oil and balance them on the battery or other mostly flat object so you can hold the funnel with one hand and pour with the other.
The “Motivx Tools engine oil funnel” approach – Since this funnel screws into the oil fill port, it doesn't require any holding whatsoever so you are free to use both hands. It seals to the engine with a rubber gasket so even if you pour oil in faster than it can drain down into the engine it won't leak. You can also leave single quarts of oil in the funnel to completely drain while retrieving and opening the next one.
