Is it OK to use 5w-20 instead of 0w-20 oil?
I'm not sure what Pennzoil means by the oil being designed for hybrids. Other than the oil having a viscosity rating of 0W-20 and having detergents, what do they mean?Jim said:Pennzoil claims they "designed" it for hybrids.
You are incorrect. Synthetic oils also improve gas mileage because they are better lubricants. One thing you have to realize is there will be no noticable change in mpg between 0W and 5W oil. This is because the second the engine is started its heat changes the 0W oil to a viscosity of 5W. Heat increases oil's viscosity. Only if you live in areas of extreme cold (high minus temperatures), will you notice a mpg hit and then only at startup. Once the engine is running 5W is just like 0W oil, with regards to viscosity.meow77 said:the only difference you will notice between synthetic and on sythetic with our cars is the frequency you have to change it
I was just relaying what's on the packaging. If you want to know what they mean, you can read about it on their website, or you can ask them.Resist said:I'm not sure what Pennzoil means by the oil being designed for hybrids.
