5W-30 is recommended in most environments; 10W-30 is recommended for very hot environments or heavy mountain driving.
I generally use synthetic 5W-30, changing it every 7,500, and have enjoyed extremely good gas mileage with no problems at all.
if it's a turbo engine you should only use synthetic oil only!! if it's a non-turbo engine a conven. oil will do.
I NEVER USE A MULTI GRADE OIL I USE A STRAIGHT 30 WEIGHT DETERGENT
The grade of oil your vehicle uses is determined by what geographical area you live in. The colder the weather the thinner the oil. The warmer it gets the thicker the oil. Most vehicles use 10-w40 grade Motor oil. Your handbook will have the specific grade that your car needs to use.
I use what the vehicle manufacturer calls for.
No, use exactly what is recommended by the manufacture.
You need 91 Octane, which you can use 93 octane and 89 octane mix. which is Premium and Mid grade fuel.
Use any 10 - 40 W oil. You can also use a single grade 40 W oil if the mower is old and much used.
It takes Exactly 8.5 quarts when performing a Oil & Filter Change. And you must use 0W-40 Grade Oil.
The oil grade is written in bright yellow lettering on the oil cap where you add the oil... I bet it's 5W-30
I use 15w40
5w30
Yes, food grade mineral oil is safe for consumption and suitable for use in food preparation.
