A diesel engine would use 15w40 a gas engine could use 15w40 or 10w40
Yes, no problem.
The one that the car's manual specifies. This will be different for every car.
Check Motor Oil . Or change oil weight, example; if you used 10w30 then used 10w40 and so on.
What year is this car? I suggest using Pennzoil 10w30.
The oil type that is used for a manual transmission will depend on the car. Most cars will take 10W30 oil.
5w20, 5w30, 10w30, 15w40 etc. It will depend on what the manufacturer recommends. It all depends on the engine,manufacturer's recommendations, type of fuel it uses (gasoline,diesel),climate conditions,etc. Too many variables.
10w30 Conventional is the standard for that year and make.
I use 10W30 Valvoline. Now have 112,000 on car so far so good .
i used a penzoil high milage 10w30. I live in San Antonio, so where you live also has to do with what weight you should be putting in your car.
only total syntetic oil if is new car and total quartz 7000- 15w40 after 100000km!
in warm weather nothing in cold weather it could be hard to start
