Well, well, well... they are both excellent oils (which unfortunately we dream of here in Italy) and from the specifications we note that: the first, Mobil 1 TDT 5W40 API CK-4 SN ACEA E7 E9 is an excellent oil for diesel engines equipped with advanced anti-pollution systems such as EGR and DPF...

Hi everyone, I didn't know in which section put this question and that's why I chose General Maintenance. I had already asked this question in another topic but we were talking about something else ... Simple and flat question. What is the difference between a 5w30 and 5w40 engine oil? I have...

Why did you use E9 oil on such an old engine? Why go to use a Mid SAPs when you can enjoy all the protection of a Full SAPs? Your Volvo probably doesn't even have a catalytic converter... This thing gives me a doubt that I would like to clear up. Is using a Low/Mid SAPs oil in an engine that...

up 😁

I live in Italy. From 1 January 2019, according to the European Standards EN 590, diesel fuel must be mixed with 7% Biodiesel. This percentage should have increased to 10% from 1 January 2020 but I believe it has not been done ...

Thank you edyvw, I admit that the subject fills me and I like it very much. :D I would like to understand how do you say that an oil is "excellent" or not good? parameters do you look at? experience? Based on what do you say I don't need the Motul 5w40? I finished the questions then 😅

Thank you for your reply, you are very helpful. I have always thought that 5W30 oils were used for fuel economy reasons at the expense of engine protection. Following your thought you wouldn't even consider this oil, right...

I was talking about more recent cars, in example, for a car without DPF I mean a good quality synthetic HDEO oil such as Mobil 1 Delvac 5w40 https://www.mobil.com/en-it/commercial-vehicle-lube/pds/gl-xx-mobil-delvac-1-5w-40

If you consider diesel engine's specifications, in PCMO we are with CF while HDMO we are far beyond with CJ-4 and CK-4

I live in Italy and the temperature in winter is around 0 degrees centigrade 🥶 and in summer 30/35 degrees centigrade 🥵. Is it true that a 5W30 oil protects up to 30 degrees centigrade? :oops:

Can I ask you why? so I can understand your reasoning :) Thank you very much

Hi everyone, this is a harmless question and I don't want to be argumetative. I am curious and want to learn. Some time ago I remember that a guy gave me a speech about motor oils. According to him Heavy Duty Engine Oil were also good for Passenger Car and also had better performance. He...

Regular street driving ;)

Oil and filter changed today. :cool: My girlfriend's Polo thanks 😁

It may seem like a simple question to you but I want to learn :) Staying between Mobil 1 ESP 5W30 and Mobil 1 ESP 0W40 I ask you based on what you would choose one or the other. Beyond the fact that now neither oil has the BMW longlife 04 specification anymore, but as mentioned above, both...

My BMW 320d has the N47D20 engine. Would you use the ESP 5w30 or ESP 0w40?

Thank you for the answers. Are therefore only commercial agreements. 💸 I also ask this, I am sure that for a time this oil also had the BMW Long Life 04 specification. https://www.mobil.com/it-it/passenger-vehicle-lube/pds/gl-xx-mobil-1-esp-x3-0w-40-- Could this be okay too? Would it be...

Hi guys, last year I used this oil in my BMW 320d F31 because it had Long Life 04 specification ;) I bought this same oil last week (for another car) and I noticed that this specification is gone :eek: - looking on the internet you can find photos of bottles with the specification and others...

A somewhat precise question. I noticed that there are currently two of Mobil 1 ESP 5w30. This is also called Mobil 1 ESP 5w30 Forumula Mobil 1 ESP Formula 5W30 (151055) And what looks like a substitute called Mobil 1 ESP 5w30 Mobil 1 ESP 5W-30 (154296) Does anyone know if there is a real...
