10w40 in an engine from Belgium
Hello, again, guys
So, I am set on buying this car in Belgium (near Brussels), but I have this uncertainty, and I really need your input there.
the guy that sells it to me is very kind and he answer all my requests. among others, he sent to me any service documents he has from the garage(s) he serviced the car (it was always a Honda service). But I cannot understand this thing. Why on earth did the Honda guys put 10w40 oil in this engine in the first (recorded) maintenance entries? (at 15.500 km and 35.100 km). After that they changed with 5w30 at 57.000 km. and then again 10w40 and then 0w20, 5w30...? All the official answers from Honda (customer services) was nothing more than: „As the owner’s manual tells you, the recommended engine oil type is 0W20. What we can provide you is the information above.”
Now, is it a practice in Belgium? Is it an exception? what did your garage put in the engine? and why did they used such a thick oil? It has smth to do with the outside temperature in Belgium?
And, most important, HOW MUCH THIS AFFECTED THE ENGINE?
I list here the resume of the maintenance in the Honda garages, as it shows on the papers (only main items included):
7/11/11 15.500km - oil 10W40; oil filter
16/11/12 35.100km - oil 10W40; oil filter; air filter; polen filter; brake pads;
5/11/13 57.100km - oil 5W30; oil filter;
13/4/15 75.251km - oil 10W40; oil filter; air filter; polen filter; brake pads; cleaning of injection system; heat cleaning; brake fluid;
30/5/16 94.650km - oil 0W20; air filter; windscreen washers; pollen filter; update HDS
27/3/17 113.231km - oil 5W30; oil filter; brake pads; update HDS
26/7/17 119.016km - transmission fluid; frictieschijf; druckschijf; speciale kogellager; oil seal;
24/9/18 - heat shield
5/31/18 137.773km - oil 5W30; sparks; oil filter; pollen filter; air filter; update HDS
What do you think about this service plan (service interval, materials used)? maybe compared with what you have. I appreciate very much your answers!
I already arranged the trip to see the car and everything else seems fine, but I have this annoying exclamation sign in my mind about this.
