What’s up, guys? In this DIY, I’m changing the engine oil on my Toyota Hilux Conquest, but the steps are pretty much the same for the 2015-2025 Hilux, Fortuner, and Innova. I’ll show you the tools and supplies I actually use—correct engine oil (check your owner’s manual for API level and viscosity), the matching oil filter, and most importantly, a new drain plug gasket. I also use gloves, a funnel, an oil filter socket, a 14mm socket for the drain plug, and a drain pan. If you need more clearance, you can jack it up with jack stands, but in my case I have enough space underneath. I walk you through the process step-by-step: remove the oil filler cap first, drain the old oil, clean the drain hole, make sure the old gasket is removed, then reinstall the drain plug with a new gasket and snug it down (no need to over-tighten). After that, I locate and remove the oil filter near the exhaust on the passenger side (LHD), prefill the new filter (not all the way, since it’s diagonal), and add oil to the O-ring before installing it hand-tight. I also show how I check the dipstick level and inspect underneath for leaks. Lastly, I talk about oil change intervals: around 5,000 km for conventional, 7,500–8,000 km for semi-synthetic, and 10,000–15,000 km for fully synthetic—though I personally shorten mine (around 7,000–8,000 km) because I do off-roading, overlanding, and camping, which adds stress and load.
