I use 10w-30 Mobil 1 SuperSyn oil. in my car for summer time. One mechanic told me that if you use this oil for maxima it will cause the car to use more Gas.... IS that ture??? The reason I use this oil is that in summer the Oil becomes very thin. And I think it is a better Protection for summer time. In winter i use 5w-10 same type of oil.

Thanks In Advance.

 

i use 10 w30 and i dont burn any extra gas.

 

I use this:

 

Yes, your fuel consuption will increase slightly by using a 10W-30 over a 5W-30. The difference will be greater in colder weather and you probably won't ever notice it unless you religiously track your mileage.

Mobil 1 5W-30 is fine for year round use, as it is still a 30 wt. oil. If you're worried about the oil being to thin you should switch brands, M1 is notoriously thin in all the weights compared to the other brands.

 

What about Pennzoil Synthetic 10w30? Is that a good oil?

 

I always use Mobil 1, but this time I used 15w-50 i thought Id try it. cant tell a difference from 10w-40. Mobil 1 is very nice though

 

Hopefully you are doing frequent oil changes (< 3k) because otherwise you are doing nothing but prematurely wearing out your oil pump and artifically increasing your viscosity outside of what is needed.

 

I had no idea! thanks for the tip

 

I have been using Mobil1 10W30 since I bought my Max.
