The LaCrosse uses engine oil with a viscosity grade of SAE5W30. In extremely cold regions where temperatures drop below -29°C, SAE0W30 oil can be used. This viscosity grade makes cold starts easier for the engine in extremely low temperatures. If the engine oil filler cap has a dexos logo, it is recommended to use engine oil with dexos certification. The LaCrosse is a mid-to-high-end sedan produced and sold by Buick, equipped with General Motors' 1.5T SIDI direct-injection turbocharged engine paired with a 9-speed HYDRAMATIC intelligent transmission for efficient driving. The vehicle dimensions are 5026mm in length, 1866mm in width, and 1459mm in height, with a wheelbase of 2905mm.

I've been driving a LaCrosse and using 5W-30 full synthetic oil for years, and the engine runs exceptionally smooth. This oil has moderate viscosity, protecting parts from deformation in summer heat while ensuring smooth cold starts even in sub-zero winters. The official manual clearly states that 5W-30 meets Dexos1 standards, which is also recommended by General Motors themselves. I never buy random oils from roadside shops, preferring Mobil or Shell brands—a 4-500 RMB barrel isn't expensive, and one change lasts 8,000 to 10,000 km. Money-saving tip: stick to regular maintenance without delays, otherwise engine oil burning or soaring fuel consumption will lead to major repairs. In short, choosing the right oil makes the car durable, saving money and peace of mind.

I just bought a LaCrosse and got used to checking the user manual first, which confirms the use of 5W-30 full synthetic oil. The standard viscosity ensures top-notch engine lubrication and reduces friction noise. Don’t skimp on quality when choosing oil—I searched for 5W-30 on e-commerce platforms and picked certified brands like Castrol at reasonable prices. DIY oil changes are quite simple; with the right tools, it takes about half an hour, but be careful not to overfill. For regular maintenance, it’s recommended to check every 5,000 km to avoid degraded oil damaging the engine.

What Causes the ABS Light to Illuminate in a Jaguar?

ABS light illumination can occur in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly lit (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the contaminants from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal operation. Cause 2: Poor signal transmission due to loose system wiring connections or poor contact in the ABS relay, leading to system malfunction. Solution: Inspect wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical components are in use, the battery voltage drops below 10.5V. As engine speed increases, voltage rises, and the ABS light turns off. This may also occur due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains lit after engine startup until the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor electrical connector contact in the ABS hydraulic valve body; ABS control unit malfunction. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary; check for enlarged connector gaps; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's specified tire and wheel rim specifications, typically listed on the fuel tank cap sticker. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and manually push the brake switch linkage fully downward, then release the pedal to complete self-positioning; replace the brake light switch if necessary. If the ABS warning light is illuminated, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.
