You can even go thicker mate! "may also be used where 25w60 and SAE 50 are recommeded".Yep, Penrite HPR 40 25W70

I am just asking since apparently that is consensus among some. All Euro engines run on heavy oils, no exceptions.
Pennzoil PlatinumWhat was that TV commercial where the engine jumped out of the car and went tearing down the street because it wanted a certain oil?

Yes they do. There is no "apparently."Apparently not...

Clearly not. VW, Audi, Porche...Yes they do. There is no "apparently."

All specd. for heavy oils too.Clearly not. VW, Audi, Porche...
Were heavier oils the quieter ones?^^^^↑^^^^^^^^^^^^^^^^^^^^^^^^
Post of the month winner thus far.
I will say that certain oils have run quieter in my car than others. Why? I don't know. I do think even the louder ones were working as they should. No doubt.
I do like quieter running if I have my way.
It's not a problem as long as the engine from an engineering perspective can handle it. People erroneously assume manufacturers purposely choose lighter weight oils in order to sacrifice engine life for fuel efficiency. There's zero proof of that. Yes some engines may have been initially designed/tested on a 30w/40s but at the time were never tested on a 20w due to a lack of a standard or financial incentive to develop one.Yes, beating a dead horse here. I’m not looking for an argument but am curious. It is often cited here that engines can handle running a wide viscosity range of oils, which I agree with. But for some reason 0w20 (or thin oils in general) are viewed as the devil and shouldn’t be used in engines that previously specified a higher viscosity.
Example: the VW / Audi 1.4 TSI and 2.0 TSI. They previously ran 502.00 (30-40 grade) but now run 508.00 (0w20). So again, if engines can handle operating under such a large viscosity range (think thick oil when cold and thin when hot, which is quite the spread in CST measurement, and they DO handle that viscosity difference well)...why would it be detrimental to that engine to drop the grade down to a 20 from a 30? That is only a few CST thinner at operating temp (12 cst for 30 and 7ish cst for 20). That seems negligible IMO
Honest question.
Actually there is only proof that they select thinner oils for fuel economy.It's not a problem as long as the engine from an engineering perspective can handle it. People erroneously assume manufacturers purposely choose lighter weight oils in order to sacrifice engine life for fuel efficiency. There's zero proof of that. Yes some engines may have been initially designed/tested on a 30w/40s but at the time were never tested on a 20w due to a lack of a standard or financial incentive to develop one.
The reality is that almost every major engine failure is due to either poor material choices or poor design rather than the choice of oil weight.
*I mention ambient temps as the Hyundai owners manual mentions using 5W30 over 5W20 in summer time temps .Temps inside the engine could be 400F+ in some parts and 230F+/- avg oil temps ... I wouldn't worry too much about ambient temp.
I have 2 cars that OM recommends 5W20 and 0W20 in US. One is a truck with over 10K towing capacity. The manufacturers don't think ambient temps in US will be an issue and neither do I except i prefer a thicker oil in general and especially if I'm towing.
Yes, some owner's manuals list a specific temp range especially older manuals and some newer ones show xW20 is good for all temp ranges but also allow higher viscosity over certain ambient temp and/or operating conditions.*I mention ambient temps as the Hyundai owners manual mentions using 5W30 over 5W20 in summer time temps .
It is when you turn the A/C onYes, some owner's manuals list a specific temp range especially older manuals and some newer ones show xW20 is good for all temp ranges but also allow higher viscosity over certain ambient temp and/or operating conditions.
I have all of those owner's manuals. The idea is that in general, the hotter the engine, the higher the viscosity. Engine heat can come from high speed/rpm, towing, load, higher ambient temp, etc. However ambient temp impact is not as significant as others.
That's right. No A/C during summer it adds more load to engine. Roll down the windows and turn the heater onIt is when you turn the A/C on
