Question:
Best Oil for a High-Performance, High-Heat Engine
Hello, I own a 2006 Dodge Charger SRT8 with the 6.1L Hemi engine. The car currently has about 3,300 miles on it. This is a car that is stored in my garage and I only drive on occasions in good weather during the spring, summer and early fall. I will never put more than 2,000 miles on the car in a given year. My primary concern is long-term engine protection and valve train protection. The engine runs hot and the oil temperatures frequently range from 220°-240°. What is the best synthetic oil you recommend to protect my engine for the long haul? I own a few classic cars and plan to own this for 30-40 years. I am not concerned with increasing the miles per gallon, just maximum engine protection. Friends have recommended that I use your Mobil 1 Turbo Diesel Truck 5W-40 oil because of the high heat protection that it offers. What oil do you feel will offer the greatest long-term protection for this high performance, high heat engine? Thank you.

Answer:
We recommend you use Mobil 1 0W-40. Look at the credentials this product carries and you will quickly understand our recommendation. In addition to providing outstanding engine protection and performance as a 0W-40, it also provides a wide range of temperature protection.  At low temperatures it protects as a 0W oil, providing good low temperature pumping and cranking, and as an SAE 40 grade oil, it provides excellent high temperature oil film strength and protection.  It also happens to be the product recommended specifically for your vehicle.
