Hi guys ! I am new here..
I need Help to decide ... I have Mercedes E430 4matic 2001, it has 127788 miles on it...
I bought last summer .it was poor maintain because it had some oil build up on valve covers.. iv cleaned last summer . I only used synthetic oil Pennzoil,Mobil1 and now I run Liqui Moly ...
My car burn 1qt per 1000 miles ... Mobil1 was worst 1qt per 700 miles...
Now i wanna switch to Castrol GTX High mileage 10W40
Here is the question...
Can I run GTX HM now and when winter comes can I switch back to the 5w40 Syntetic???????
And how well 10w40 will be at -5 F ???? I am living in New York State...
Thank you..
