Mobil 1 High Mileage Synthetic 10W30

Received this question about Mobil 1 High Mileage Synthetic 10W30 and thought I would share it with you.  Please provide your reply in the comments at the bottom.

Hey jesse, I put mobil 1 high milage synthetic 10w30 cause my truck has 77,500 miles on it. There was 3,300 miles on castrol 10w 30 regular oil before the change. That’s normally the oil I use in my vehicles so I decided to try synthetic oil. I have a friend that’s a mechanic on printing presses and he knows a guy that works at a refinery and was told castrol was the best from refining process from different types of oils.

Well, getting back to the oil change I checked it at 3,000 and it still looked ok and felt like had some viscosity left to it from feeling it on dipstick but when draining it looked not so great coming out of pan. I also had a quart of castrol 10w 30 and the synthetic I had just bought. I took both of them and put each in a cup and the synthetic had a bit more lubrication than the other and when starting truck could notice the difference in the sound and idle of the synthetic, much smoother and quieter and the synthetic looked better.

My father is a retired detroit diesel mechanic of 50 yrs and has seen allot of flaws with technology and he told me to use a good conventional oil like castrol cause hes uses it and don’t worry about it. He also said don’t believe everything you read or hear and half of what you see, lol. He said there were allot of scams out there and they don’t want you to know the truth cause to make money from you with things breaking down. He doesn’t believe in the oil or gas treatments either but I would have to disagree with him cause they helped with older high mileage vehicles I had in past. Could you tell me how many miles could I push the synthetic oil I’m using now?

My comment:

Stop and go traffic in the heat and humidity of New Orleans is considered “Severe Service”.  Stop and go is really the key to defining the tough duty on the engine oil.  As long as you run the engine for 20-30 minutes at a time to get to full temperature it will help keep the oil baked out of any condensates like water and unburned fuel.  If you really are running stop and go all the time then you need to use the shorter change interval recommended by Mobil.
