What viscosity oil should be used for CRV2.4?
3 Answers
CRV2.4's official manual recommends using 5W-30 oil, and any oil model that meets this specification can be used. The original oil brands for Toyota Corolla are Idemitsu and ENEOS. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, and Total. The viscosity of the oil changes with temperature, so special attention is needed to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand -30°C low temperatures. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in CRV2.4 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover's oil filler port, generally filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If there are leaks, perform repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
Attention all Honda CR-V 2.4 owners! The manufacturer recommends using 5W-20 or 5W-30 oil for this engine. Personally, I've been using 5W-30 semi-synthetic oil in my car. For summer road trips or older vehicles, using 30 viscosity is safer, especially for cars with over 100,000 kilometers – higher viscosity can help reduce oil consumption. Always choose oil with API SP or SN certification, and don't cheap out on off-brand products; engine repairs can be costly. Last time during maintenance, the mechanic mentioned that in northern areas with temperatures below -20°C, 0W-20 oil provides smoother cold starts. Oil change intervals depend on the oil type: mineral oil at 5,000 km, and full synthetic between 8,000 to 10,000 km is fine, but change earlier if you frequently encounter heavy traffic.
My 2012 CR-V 2.4 has hit 100,000 km, and I've mastered the art of engine oil selection. The manual recommends 5W-20 for fuel efficiency, but for older vehicles, upgrading to 5W-30 full synthetic is advised. Last time I used 0W-30 and noticed much quicker cold starts – no more steering wheel shakes in winter. Focus on oils with ACEA A5/B5 or ILSAC GF-6A certifications, as Honda engines are particular about oil. For modified intake/exhaust systems, higher viscosity like 5W-40 offers better protection. Don't randomly add additives to naturally aspirated engines – frequent oil filter changes are key. The mechanic reminded me that frequent short trips require shorter oil change intervals.
