What Types Of Gasoline Can And Can’t Be Used?

Chevy’s Recommendations

For the gasoline engines, Chevy advises using regular gasoline with an octane rating of 87 or more. The additives that you can and can not use are discussed in the sections below.

For the diesel engines, Chevy advises using the Ultra Low Sulfur Diesel that has no more than 15 ppm of sulfur in it.

Reformulated Gasoline

Reformulated types of gasoline are the ones that have additives that mainly reduce emissions and reduce carbon deposits. There are plenty of different reformulated gasolines available, which you can use. However, there are quite a few that you are not allowed to put in your Cruze as per the manufacturer’s instructions.

Fuels that contain up to 15% ethanol are okay to use while those exceeding 15% are not advised to use in your Chevy Cruze, especially the E85 which is also known as flex fuels. TOP TIER Detergent Gasoline is advised to use. You can look up this label at the fuel station to know if that fuel pump has it or not.

The manufacturer advises using a bottle of GM Fuel System Treatment Plus if the TOP TIER Detergent Gasoline is not available in your region. You can add a bottle of this alternative at every oil change. It will help clean up the fuel injectors and the intake valves. This additive will be available at the dealership.

For the diesel variants, the manufacturer advises the use of TOP TIER Diesel Fuel.

Gasoline/Oxygenated Blends Or E-85

The oxygenated blends are burned much cleaner but if the proportions of added ethanol exceed 15%, then it becomes damaging to your engine. Chevy advises against using fuel that has more than 15% ethanol. Flex-fuel, which has 85% ethanol is not an option in the case of Chevy Cruze.

Normally, if a vehicle is flex-fuel appropriate, the manufacturer will put a label on the gas cap – indicating that your vehicle has been made to handle this type of fuel.

The diesel variants of Chevy Cruze don’t support Flex Fuel at all. There are many other additives that you shouldn’t be putting in your Chevy Cruze, which we have mentioned here in this blog.

Gasoline With Added Materials

There are many additives available in the market claiming to do wonders to your engine and boost your mpg numbers but not all of them are safe to put in your engine. There are plenty of additives that Chevy is against using.

Methanol additives are strongly condemned in the case of Chevy Cruze, and the same goes for adding more than 15% of ethanol. Octane boosters are normally recommended if you are in an area where fuel quality if not up to the mark – is less than 87 of octane. By adding octane boosters only for the time being will help you reduce engine knock that happens due to low octane-rated gasoline.

The regular gasoline available at the gas station already has detergents added to make sure that the quality meets the required standards and the emissions are kept as low as possible. So in most cases, you wouldn’t have to add more detergents into your tank.

Shell V-Power for instance, has all the necessary additives already, so you wouldn’t need to add extra on top, and the same goes for many other distributors.

For the diesel variants, GM Suggests using the TOP TIER Detergent Diesel additive. If in case the additive is not available, an alternative “ACDelco Diesel Fuel Conditioner” can be used instead. GM does not recommend any other aftermarket additive to be used in any of Chevy’s lineups, including the Chevy Cruze.

Gasoline must not be added in the diesel variant, if added accidentally, the vehicle must not be driven at all.

Gasoline With MMT

This is a type of additive that increases the octane rating of the fuel. However, it is not recommended by the manufacturer.

This additive MMT stands for Methylcyclopentadienyl Manganese Tricarbonyl, which damages the spark plugs and affects the emission control system performance. If the engine is damaged by using any of the additives not allowed by the manufacturer, the warranty will no longer be effective.

Similarly, the MMT should not be added to the diesel variant. It will damage the emissions control system on top of damaging the spark plugs. 

Biodiesel

This is the type of fuel that is used as an alternative to diesel fuel. It is mainly produced from vegetable oil, waste cooking oil, tallow, animal fats, etc. The refined – ready to use product is known as biodiesel. Biodiesel is normally mixed with regular diesel about 5%. It has been shown to increase the fuel economy and on the other hand, lower emissions.  

Chevy advises not to use more than 20% of biodiesel mixed with the regular diesel – doing so will result in increased debris and will also cause the filters to clog up much earlier. To compensate, you would have to keep on changing oil filters regularly.

What If I Hear A Knocking Noise From The Engine After Refilling

According to the owner’s manual, low-quality fuel caused engine knock, and if you hear a knocking noise from the engine, then add gasoline with higher octane. Ideally, use mid-grade or premium for the time being. With this measure, the knocking noise will be reduced.

A faint knock coming from the engine is usual, but if you hear a loud knocking, your engine needs service even though you had high-quality gasoline.
