There are certain factors that can help you distinguish between synthetic oils, this is crucial when choosing a brand for your vehicle.
1. Full Synthetic and Synthetic Blend Oils
Fully synthetic oils are made from synthetic materials while synthetic blend oils are mixtures of standard motor oils and synthetic oils.
For anyone upgrading from the standard oil to the synthetic oil, ensure to drain the oil before the introduction of the latter.
Check to see if it’s a newer model engine (usually fro year 2000) before proceeding.
3. Viscosity Level
This is the thickness level of the oil and since oils get thinner during intense operation, heavy-duty engines require thicker oils to function at optimal levels without any form of wear and tear.
When the oil is also too thick, this could prevent easy engine start-up so ensure to get engine oils with precise viscosity which is often present on the vehicle’s manual.
For those in hot environments that often haul heavy loads, ensure to get oils with a slightly higher viscosity, and for light errands in cold climates, get one with slightly lower viscosity.
4. Additives and Brands
The additives in this oil makes it stand out and there are several types of additives in synthetic oils while each manufacturer has its unique formula.
The corrosion inhibitors help to protect your engine from corrosion
Dispersants are needed to reduce the clumping of particles and sludge build-up
Anti-foaming agents are required to prevent oil from foaming
The conditioners help to soften seals and increase expansion and contraction
An antioxidant is necessary for prolonging the oil’s lifespan
Not all expensive oils deliver the best performance so ensure to stick to the auto manufacturer’s guideline.
Pick the right motor oil based on your mileage.
Change your filters always
Get acquainted with the oil warning lights
Check your oil level regularly
