Buying Guide for Best oil for predator 3,500 generator

Your generator will most probably use the same synthetic oil as your car. For most generators this happens to be the synthetic 5w 30 variety. Motor oil is vital for your generator as it helps keep all things well lubricated and washes away the sludge found in the engine. The oil will also keep help in heat dissipation by moving heat from the engine into the oil pan. Here are some key factors you should be considering when purchasing motor oil.

Check the generator manual

This is the first place you should go for information in regards to the right motor oil to use. Most of the portable generators come with a user guide that shows you how you should maintain your generator. The manual section features some of the spare types you should go for during maintenance. If you have lost yours you can find some of these information on the generators website.

Engine type

The next thing you should put into consideration is the generator type. There are usually two varieties – two and four cycle engines with the four cycle being the most popular. A closer inspection of most of the four cycle engines will reveal that they often use the SAE 5w-30 or SAE 10w 30. This is the synthetic variations. The predator 3,500 is a 212 four stroke OHV engine and will do well with the above oil types.

Check the viscosity of the oil

The oil viscosity determines the operating temperature of the oil. This shows you its resistance in various temperatures like extreme cold or hot. The first letter in motor oils starts with the letter W and denotes its viscosity in winter conditions. The second number is for hot weather. Overall, you should go for higher second numbers as it means the oil remains thick even under hot weather conditions. This enables the oil to continuously keep your engine well lubricated. If you are going to be using your generator in cold conditions then you need to keep a close eye on the first number. This is why SAE 5w 30 is an excellent choice as it factors both weather extremes.

Get oil from reputable brands

There is a lot of competition in the motor oil market and as such you need to be careful where you purchase your oil. Oil brands with a long history of supplying petroleum products tend to be the best as they have also being certified by the Society of Automotive Engineers (SAE). Some of these brands include Shell, Castrol, Shaeffer, Mobil among others.

Type of motor oil

In your search for the right motor oil for your generator you will confronted with two main types of oil – conventional and synthetic. The conventional oil is the standard oil you find for everyday use. It is also called the standard oil. The oil is mostly used for applications with low mileage. The greatest benefit for the conventional oil is that it is pocket-friendly. But, it may not be the best option for high-performance engines. The next most common type of engine oil is the synthetic oil which is of a higher quality and comes with additives. The latter are special compounds added to oil to make it better by offering better protection against wear and sludge. Synthetic oils cost more than the conventional oils. For your Predator generator it would be recommended you go for the synthetic type.


The predator 3,500 generator is an excellent portable generator that you can attach to your RV or use it at home during blackouts. The best oil for this generator is the SAE 10w 30. While there are many brands that you can use for your generator the general consensus among Predator 3,500 owners is the Castrol 03084 EDGE 5w 40. The oil offers superior protection against sludge formation due to its special titanium technology. This is a synthetic oil so you are assured of its quality. Castrol is also a reputable brand known for superior oil products.
