FAQ:

Q: What is the difference between a 5w40 and a 15w40 oil?

A: 5w-40 has a broader operating range than 15w-40. Unless you’re penny pinching or you’re misinformed about synthetic oils, it’s stupid to pick the 15w-40 option. There is a single benefit to 15w-40 oils though, they will maintain their 40 weight operating viscosity longer than an oil that starts at 5w.

Q: What is the best synthetic diesel oil?

A: AMSOIL remains the best synthetic diesel oil on the market. The heavy duty oil resists breakdown from factors like heat, oxygen, and chemicals up to 10 times longer than other diesel oils.

Q: Who makes the best synthetic motor oil?

A: Pennzoil’s unique refining technology that turns natural gas into a full synthetic motor oil makes this one of the top-rated oils on the market. This is because the process creates a base oil that is 99.5 percent pure.

Q: What is 5W – 40 oil?

A: 5w 40 is basically a terminology to define the grade of lubricating oil. W here stands for ‘winter ‘ grade. If oil has grade like 5w 40 then it a multigrade lubricating Oil but if it has only single number like 30,40 etc. then it’s a mono grade Oil.
