Engine Oil Consumption When Changing Oil Brands
Oil consumption is normal and varies in all engines depending on the manufacturers and their designs. You can ask the dealer or manufacturer to provide you with their guidelines for what is considered normal oil consumption in their particular model engine. When changing oil brands, such as changing to a premium oil like Schaeffer oil from any other brand you can expect little change in oil consumption rates. This can be especially true if the engine is new or low miles or well maintained. Although there is a small percentage of engines that will experience a noticeable change in oil consumption rates.
Increased oil consumption can be attributed by these factors:
- The previously used engine oil may have had buildup deposits in various areas in the engine which can act as a seal which a premium oil can dislodge with their additive cleaning agents.
- When engine oils are mixed there can be a complex chemical reaction that can lead to short a term increase in oil consumption rates.
Once the process of deposit removal and engine varnish cleaning is accomplished with a premium oil like Schaeffer's the engine seals will begin to normalize and the oil consumption rates will begin to normalize. This process is where the new oil has fully formed a full seal. This process can vary in time from engine to engine.
Other problems can attribute to oil consumption that are not related to the changing to a premium oil like are as follows:
- Broken piston rings.
- Worn valve guides.
- Gasket leaks.
- Worn bearings.
- A highly worn engine.
Note: It is important to note that premium engine oils will not cause increased oil consumption in engines that are well maintained and in good condition.
