The Best Synthetic Oil Review and Buyers Guide 2019

The Best Synthetic Oil Review and Buyers Guide 2019

Previously, there were handful choices of Synthetic Oils to choose among, but now there are a lot of types that may confuse you. The main goal of this article is helping you to choose the most excellent Synthetic Oil according to many factors.

Vehicles couldn’t move without high-quality motor oil. Ignoring this fact may cost you high maintenance costs or losing your engine. Using such ordinary oil may damage your vehicle. You should use the synthetic oil that got approval from certified or trustworthy manufacturers and of course SAE (the Society of Automotive Engineers). I mean the honest recommendations, not the commercial agreement between brands.

Is there a fixed criterion to know the best synthetic oil for your vehicle? Do you check the price or quality?

Actually, you can’t determine what the best is unless you make tests. You have to do a lot of tests, in fact. Scientific tests uncover the myth of commercials. So, it will be clear to you to know the wheat from the chaff. Here, I collect a package of The 7 Best Synthetic Oil products that are well tested and got more than 4 stars customer reviews on Amazon.

Mobil 1 94001 5W-30 Synthetic Motor Oil - 1 Quart (Pack of 6)

Product Description

  • Seal conditioner, helps prevent leaks
  • Advanced full synthetic formula
  • Extra anti-wear additive

Mobil 1 is a 106 years old company. This reputation deserves a certain level of quality. Think about such synthetic motor oil like Mobil 1 94001 5W-30 that offers these benefits:

  1. Mobil 1 5W-30 is the most wide-range uses: This synthetic oil is the most widespread synthetic oil. It works with all modern vehicles include pickup, turbocharged, small vans, passenger cars, trucks, and compact cars. It is preferred at all of the previous as a high-performance vehicle engine.
  2. Mobil 1 5W-30 Works in Any Environment and Weather: Mobil 1 has a versatility that works in both cold and hot atmosphere.
  3. It is excellent for General Motor Cars: General Motor recommends Mobil1 5W-30 for its vehicles in cold places in the United States. Mobil 1 has the best viscosity for GM cars.
  4. Long-time to change the Oil: According to Amazon’s customer reviews, Mobil 1 5W-30 synthetic oil doesn’t need to be changed as frequently as other types of synthetic motor oils.
  5. High protection from Suspend Solids: Are you worried about sludge? With Mobil 1, don’t worry about such a thing. It protects you from all harmful solids.
  6. It Saves Money: If you check this offer (link above) you will touch that it provides 1 Quart (Pack of 6), and this offer saves a lot of money.
  7. Amazon Customer Reviews: Mobil 1 5W-30 got 4.8 stars 596 customer reviews (86% of them are 5 stars evaluation).

Personally, I recommend this choice. Mobil’s reputation protects my vehicle and I trust Mobil’s quality. But although this high quality, it is not recommended for 2-cycle engines. This synthetic oil is perfect for cars only.

Also, it looks like that Mobil 1 5W-30 is better in a cold environment more than hot. Anyway, it’s acceptable compared with the wide range of use.

What We Liked

  • Most widespread synthetic oil, many people enjoy this one
  • Highly rated
  • Best formula for GM motors

Shell is another deep-rooted company. Shell Rotella is the second in this list and I think it will be the second brand choice if you don’t like Mobil.

Shell Rotella T6 5W-40 is a high protection synthetic oil formula for engines. It designed basically to give your engine the utmost protection ever. It is the hard work synthetic oil that works under any condition (dusty, muddy, steep and cold environments).

So, we can summarize the benefits of Shell Rotella T6 5W-40 as follow:

  1. Extreme Temperatures Fighter: Rotella T6 works under the extremely high and low temperatures. Imagine a temperature as cold as -30F or hot as 400F with T6. Don’t worry, as I mentioned above: It is the hard work synthetic oil and the flow of the Shell oil isn’t affected by high/low temperature whatever it is.
  2. It can work well with some motorcycle models: Mobil1 doesn’t work completely with a motorcycle but Rotella T6 is compatible with some models. So, it’s recommended to check your motorcycle engine compatibility with Shell Rotella T6 oil before buying it.
  3. Shell Rotella T6 is Fully Synthetic Oil: It’s not made from carbon petroleum products. So, it is fully synthetic. This benefit reflects the flexibility of such synthetic oil, that it can be adjusted according to any condition without reducing the level of performance.

But the last note you should put in mind if you work in the field of construction. Shell Rotella T6 Synthetic Oil is not suitable for gear motors. T6 is a very thinner synthetic oil compared with the thickness that these motors require.
