Does the Camry 2.5L fuel version experience oil dilution?
2 Answers
The Camry 2.5L fuel version generally does not experience oil dilution under normal circumstances. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts, as well as to remove sludge and varnish from the engine. Taking the Camry 2021 2.5G Luxury Edition as an example: it is a mid-size 4-door 5-seater sedan under GAC Toyota, with dimensions of 4885mm in length, 1840mm in width, and 1455mm in height, a wheelbase of 2825mm, and equipped with an 8-speed automatic transmission.
As a long-time owner of the Camry 2.5L gasoline version for over three years, I occasionally encountered increased engine oil levels during northern winters. The 4S dealership explained that direct injection engines may not fully burn fuel during short-distance driving in cold temperatures, causing gasoline to mix with the engine oil and raise the fluid level. Later, I changed my habits by taking a weekly highway trip or running high RPMs for a few minutes, which significantly reduced the issue. The key is to regularly check the dipstick and ensure the oil level doesn't exceed the maximum mark, as overfilling can impair lubrication and damage the engine. During routine maintenance, remind technicians to inspect it—some Toyota models from certain years have ECU upgrades that can improve this. Generally, it's not a major concern for normal driving, but don't delay if you notice abnormalities; address them early.
