Check your owner’s manual before buying engine oil additives. For routine service, use the specified oil and filter at the recommended interval. If you have low oil pressure, rising consumption or a persistent cold-start problem, have the cause diagnosed before choosing a treatment.

Check your manual before treating the oil
Read the oil viscosity, required approvals and additive guidance for your exact engine. Some vehicle makers explicitly prohibit supplemental oil treatments. The Ford maintenance instructions are one example.
- Check oil level using the method in the manual. Compare the recommended oil, oil capacity and filter before adding anything.
- If the vehicle maker permits treatment, read the exact product label for sump size, mixing directions and exclusions. A shared wet clutch can have a separate oil requirement.
- Account for additive volume in the final fill and use the vehicle’s level-check procedure. Handle and dispose of oil and containers as directed.
What to check when oil consumption changes
Use the vehicle’s specified level-check procedure and record changes over distance. Persistent consumption, leaks, warning lights or unusual noises can require mechanical diagnosis. For oil selection, see the motor oil specification guide and the diesel engine oil guide. The engine flush guide covers short-term cleaning procedures. For rough running in a gasoline engine, also check the ignition service schedule and the spark plug fitment guide.
Archoil AR9100
Archoil’s application guide distinguishes standard rates from examples for certain large-capacity diesel engines. Use the exact sump capacity and label. Have a cold-start fault diagnosed before assuming an oil-side injector problem.
LIQUI MOLY MoS2 2009
The LIQUI MOLY US page identifies code 2009. Verify the exact market directions and equipment manual before use, especially when an engine shares oil with a clutch.
LIQUI MOLY Cera Tec 3721
LIQUI MOLY lists product code 3721 and its application limits. Cera Tec and MoS2 use separate formulations and directions.
Lucas Heavy Duty Oil Stabilizer 10002
Lucas identifies 10002 as Heavy Duty Oil Stabilizer. A stabilizer takes up part of the oil fill. Verify that the vehicle permits the product before changing the specified oil mixture.
MotorKote Hyper Lubricant MK-HL01G-04
The MotorKote gallon page matches the part code. The application guide separates engine, bypass and wet-clutch use. Check the exact label and the equipment manual.
Hot Shot’s Secret Stiction Eliminator HSS32Z
Hot Shot’s Secret identifies the quart SKU and lists different first-use and follow-up guidance. Check the delivered label and oil capacity. A change in starting behavior alone does not identify a failed or repaired part.
BG MOA 110
BG publishes a MOA 110 page and Advanced Formula directions. Check the exact can and application, since the listing image and current label can differ.
REV X High Performance Oil Treatment
REV X lists a 4-fl-oz bottle. The retailer describes the linked ASIN as a four-pack. Confirm the selected package and measure the treatment by oil capacity.
Rislone Hy-per Lube HPL201
The Rislone technical sheet gives 1 qt in place of 1 qt of oil for compatible 4–6-qt systems. Check the manual first and follow the exact bottle, including its fill limits.
FAQ
Do I need an oil additive at every oil change?
Follow your vehicle’s oil specification and maintenance schedule. If the manual prohibits supplemental oil additives, use the specified oil and filter.
Can I add an oil treatment to a full sump?
Account for the treatment volume and follow the vehicle’s fill and level procedure. Never exceed the specified oil level.
Can I use Cera Tec in a wet-clutch motorcycle?
LIQUI MOLY excludes wet-clutch applications for Cera Tec. Use the oil specified by the motorcycle manual.
Will an oil additive repair a persistent low-pressure warning?
Follow the vehicle’s warning instructions and have the engine diagnosed. A treatment cannot identify whether the issue is the oil supply, sensor, pump or another fault.
Are oil treatments and engine flushes used the same way?
Check the exact label. A pre-change flush may be drained at the end of a short procedure. Other products have directions for a regular oil fill.
