This means the engine might not be as well-protected during high-stress scenarios, such as towing or driving in hot climates, compared to using a full synthetic fill. First, ensure the new oil meets the same API service rating as the old oil; never mix different viscosity grades or oil categories (e.
How Mixing Oils Accelerates Additive Depletion
Consequently, the time or mileage until your next oil change should be adjusted accordingly, reverting to the schedule recommended for conventional oil rather than the extended schedule provided by full synthetic. By introducing conventional oil, you accelerate the depletion rate of the synthetic additives because the base stock breaks down faster.
The short answer is yes, it is generally safe to combine the two, but understanding the implications is crucial for maintaining engine health. Oil change intervals are determined by the depletion of additives and the accumulation of contaminants.
How Mixing Oils Accelerates Additive Depletion
Drivers often question the validity of mixing synthetic and conventional oil , especially when topping off between changes or in emergency situations. Extending the time between scheduled services by a few hundred miles.
