Yes it is.
10w40 or 10w 30 depending on the temperature, but yer finee
Yes it is fine to use 10W-40 oil
10W-30 or Straight 30W, the Walmart or Meijer brands are ok
Yes, unless you live in a warm climate then you can use a 10W-30.
All Kia products are designed to be operated with 5w-20. In an emergency you can add a different oil weight to get you by, but use as little as possible for as short a time as possible. Change the oil and filter as soon as you can and replace oil with 5w. The heavier oil will not hurt your car, HOWEVER, the tolerances on these engines are so exact that running a heavier oil in your car will actually expand the area between the lubricated parts. What does this mean to you? Extended use of the heavier oil will cause oil loss and smoking as the lighter 5w oil leaks into the cylinder and is burned at combustion.
Factory teck sheet recommends useing 10W30 in the HOT months ONLY. 5W30 in the cold months is recommend.
10W-30 for gas engines for outdoor temperatures between 0 - 100 degrees. 5W-30 for gas engines if outdoor temperature runs consistantly lower than 32 degrees. Conventional or synthetic oil is ok.
usally the proper oil will be listed in the manual or on the oil cap. if it has alot of miles uses 10-30 if it has a ton of miles 10 40 wont hurt, if miles are still low and egine is well kep, and doesnt leak or burn oil 5 30 may be ok
No, it is not okay to use an oil not recommended by Honda. You use the snowblower in cold temperatures that is why Honda recommends a 5 weight oil. There's no reason whatsoever to use 10W-30 weight oil. Use 5W-30 as Honda recommends and nothing else. I also recommend you use a 100% synthetic oil in any air cooled engine.
If it drops to 35 PSI at an idle, but comes up to full pressure when you're driving, it's ok.
Use the exact weight oil in your engine as is listed in your owners manual. Most major brands are good. I use Pennzoil and have for over 30 years. Never had an internal engine problem. Also use a good oil filter. Purolator & Wix are a good choice.
