According to the 2006 Lincoln Navigator Owner Guide : The vehicle is designed to use " premium " unleaded , 91 octane or higher
The 2007 Cadillac CTS with a 2.8 V6 engine is designed to run on regular unleaded gasoline with an octane rating of 87. While using premium unleaded gas may provide slightly better performance and fuel efficiency, it is not required. For optimal engine performance and to avoid unnecessary expenses, regular unleaded gas is sufficient for this vehicle. Always consult the owner’s manual for specific fuel recommendations.
A 2004 Cadillac Escalade typically uses premium unleaded gasoline with an octane rating of 91 or higher. Using premium fuel can help optimize performance and fuel efficiency for the vehicle's V8 engine. However, it can also run on regular unleaded gasoline (87 octane) if premium is not available, though this may affect performance. Always refer to the owner's manual for specific fuel recommendations.
The recommended fuel for this vehicle is Premium Unleaded but Ford does not say it is mandatory. So, more than likey, you can burn Regular Unleaded with a loss of power as the fuel managment sytem will adjust for the lower octane fuel. I am not 100% sure about this on this vehicle so contact your local Ford dealer to verify that I am correct.
This vehicle requires Premium Unleaded. You can try using 89 Octane and see if it pings or not. If it does then you will have to move up to 91 Octane. Do not use Regular, as it will cause pre-detonation and may do harm.
Use exactly what the owner's manual states. If you do not have one, you can obtain one from your dealer or a salvage yard. This is word for word what it says in my manual: Fuel selection: Use only UNLEADED fuel, Research Octane No 91 (Octane Rating 87) or higher. For improved vehicle performance, the use of Premium unleaded gasoline with a Research Octance No of 96 (Octane Rating 91) or higher is recommended.
Any Japanese petrol driven motor vehicle made post 1985 should run on Unleaded without modification
The 2003 Volkswagen Passat typically requires premium unleaded gasoline with an octane rating of 91 or higher for optimal performance. However, it can also run on regular unleaded gasoline (87 octane), but this may lead to reduced engine efficiency and performance. Always consult the owner's manual for the most accurate fuel recommendations specific to your vehicle.
Yes, the 97 Mitsubishu Eclispe does run with unleaded gasoline fuel; however, it can run fine on normal fuel as well the unleaded fuel. It does not affect the performance of the vehicle.
