Mobil 1 AFE. Huge difference.

[HotBoxer]

Yesterday I went to get winter oil (0W30) put into my Sonic. I got a jug of Mobil 1 Advanced Fuel Economy, normally expensive stuff but I got it at 40% off.

Recorded the trip there (30 mins highway driving, on cruise control at 100km/h, temperature below freezing, no wind). Got 7.8L/100km (30MPG).

After the oil change I reset and did the exact same trip home at the exact same speed. Checked again...6.7L/100km (35MPG)! Even if you account for inaccuracies, that's pretty good...

ooh... if our turbos like this make we should all give it a try.

I think I'm going to keep it in my Sonic through the summer too. The flash point is 226 celcius and our engines run at about 105, I doubt there will be any circumstances where my engine is running a hundred degrees hotter than usual.

It is extremely hard to determine actual differences in fuel economy over such a short distance. Too many variables - wind (even slight differences), elevation changes based on different directions, traffic, etc.

The the 0W30 is Dexos certified, so that's a good thing. I don't think it really gets cold enough in Ontario to worry about the 0 vs the 5.

The biggest difference I see in the two oils is the lower level of Zinc and Phosphorus in the 0.

Regular Mob1 5W30 has 800ppm P and 900ppm Z

0W30 AFE has 650/750

Notice the ratios of the zinc/phosphorous don't change. Zinc phosphate salt is a common additive and I believe it's used in lower amount because the lower weight oil heats faster, 150-250 ppm is insignificant. Thinner oil has been proven many times to increase mpg.
