Pennzoil platinum mpg boost

[papang]

Put in Pennzoil platinum 300 miles ago and I'm getting 3-5 mpg better than the previous oil I used (k&n) excited to try ultra platinum next I'm very pleased with the product. 2020 Impreza 5mt 100% short city driving from 22mpg to 25-27mpg.

Are you in the U.S. and experiencing the )))HEATWAVE((( like the rest of the country is?
All of our vehicles fuel economy is up in this heat.

it was actually hotter with the k&n oil but still got worse mpg

Pennzoil Platinum is the thinnest oil out of the bottle and quickly drops below grade. If you do your calculations honestly over the long term, you are unlikely to see an improvement over 1mpg. Not worth the reduced engine life IMO.

Something else is going on here. I am not convinced any oil will produce results like that.

I'm glad you are happy.

Summer blend gasoline?

 

[demarpaint]

Summer gas and higher air pressure in the tires from the heat is helping my mpg. It always does.

Many things have changed. Not least of which could be the fuel, a study I linked once showed that even at the same gas station and irrespective of summer/winter blends the energy density of gasoline varied about 4%. Without using standardized test fuel no real-world determinations are possible. Measuring a fuel consumption difference between oils requires a laboratory and using a test such as ASTM D8114 which isolates variables so that the small change isn't deep down in the noise.

Here is a partial list of some of the other things that change:

Best Brand of Gasoline

Get all my Premium at Sam's Club. Other places around here are 40-50 cents more expensive than Sam's Club premium, making it well worth driving a couple extra miles to fill it up. Get my 87 wherever it's convenient.

100% doubt it. I started using syn oil in my Yamaha in 1970 , Steen C chemical lubricant and by 1973 I was running syn oil in my vehicles engine and drive line and I never noticed a notable MPG increase.

Placebo effect

If you put in Penzoil transmission fluid, you should be able to gain another two or three miles a gallon.

Dont forget nitrogen filled tires…

Dont forget nitrogen filled tires…

I prefer hydrogen…makes the car lighter and good for 5 additional MPG.
