Is It True That ........

[Stocko6]

Is it true that once you use synthetic motor oil , you must use it the entire life of the motor?

 

[Pocket]

That's an old wives tale.

 

[98andahalf]

yea....just a way to sell product.

 

[Abrannan19]

yep..not true.

I will reccommend that you would use synthetic in a 6.0 though.

Its more of a once you use a synthetic engine oil, you will WANT to use it for the entire life of the vehicle.

The guys that are running Valvoline Extreme, ahow long are you going on your oil change intervals without having an after market oil filtration system like FS or Amsoil? Are you still sticking with 5k?

 

[Abrannan19]

I go about 8-10k
