Engine Oil Comparison oh Engine Oil Comparison

I would like to change my car engine oil.

But my friend say semi synthetic is better.

So I go to the internet and do some comparison.


FULL  SYNTHETIC  OIL:

- Highly recommended for new cars/engines under 75,000 miles — Sometimes required.

- Exceeds basic lubrication requirements

- Good for up to 7,000 miles (sometimes 10,000) which allows for longer oil change intervals

- Provides factory-like protection against corrosion, friction, & heat wear

-  Extends life of engine

- Best possible oil for your car no matter how old or new

SEMI-SYNTHETIC/SYNTHETIC  BLEND OIL:

- Can be used in cars/engines under or above 75,000 miles

- Exceeds basic lubrication requirements

- Protects against corrosion, friction, heat wear & sludge build-up

- Good for stop-and-go driving

- Has ‘seal-conditioners’ to prevent small leaks from occurring & seal pre-existing, minor leaks

- Good for up to 5,000 miles allowing for longer oil change intervals

CONVENTIONAL  OIL:

- Meets industry’s basic lubrication requirements

- Good for 3,000 miles

- Provides basic protection against friction wear
