Shell synthetic oil with any (new) oil additive?

[3246cc]

I know there are many topics about this, but this is another question.

I was wondering will any synthetic motor oil like Shell 0W30 or 5W30 and lets say some Lique Moly oil additive have any improvement in a 2.0 - 5-cylinder diesel engine?

I want reduce some noice, tear/wear and some minimum fuel consumption.

Other question; an oil additive like this, will it make the oil thicker?

Liqui Moly additive what?

Do you know what you're asking here?

Eh not really. For the price of an LM additive which i assume is that ceramic one I'd spend extra on a better oil with a better base stock. And i don't know of any LM additive that thickens but if it did then you might as well get a 40 weight oil. But what engine is this exactly and what is listed in the book. If it lists some c3 5w-30 then i'd use a 0w-40 diesel oil. The loower ash is for IF it burns so it doesn't damage the emission system as quickly as a higher saps formulation. But if it doesn't burn then it simply doesn't matter. I'd probably use a 0w-40 diesel oil. The mpg hit is basically negligible since 0w-40 grade diesels are around 13cst but 30 grade ones are around 12. Basically no difference there. Don't let the difference between 30 and 40 fool you.

I always thought noice was a good thing, why reduce it?
