I've read a lot of comments about 5w30 used instead of 10w30?
I live in Arizona. These are reasons I've used 10w30. My neighbor worked at the Ford proving grounds. Their petroleum engineer said he personally "… Wouldn't use 5w anything in any vehicle he owned.".
I had my Hyundai serviced at local Hyundai here in NW AZ every 3000 mi. The manual states 5w30. The receipt read they used 10w30. They said Winter or summer thats what we use here. Brand new car being serviced by the manufacturer they wouldn't use 5w in AZ
I change the oil at 5000 now using only OEM filters, but have switched to Mobil 1 high mileage 10w30. There's 90k on car. It has been totally dependable. It doesn't leak or burn a drop of oil. Never a warning light Combined it avg 28 mpg.
If I changed to 5w30 what benefits are possible? The next oil/filter change will take me into fall.
5W30 is lower viscosity in cold temperature startups, especially below 0F. In Arizona, 10W30 is fine. The key is frequent oil change before viscosity breakdown and dirt in the oil. 3000 miles in Arizona probably best on standard oil and can go to 5000 on synthetic or semi-synthetic.
best rated oil filters
1) Mobil 1 Extended Performance Filter
2) Royal Purple Extended Life
3) Bosch Premium FILTECH
4) ACDelco Professional
5) FRAM Standard Oil Filter
6) Purolator PureONE Oil Filter
taxis attribute their 200-400K engine life to frequent oil changes as most important
Unless you are burning oil 5w is better.
You would be putting in what the manual says. If you had a Honda the manual would recommend 5w20 or 0w20 so that is what you use. Whether you are in Arizona or East Jabip. The operating temp of the engine is 190 F
The temp outside in Arizona reaches that? Think.
In colder climates you'd want to use 5w 30w oil.
It probably doesn't matter where you live.
- My mechanic put 5w30 oil in my ford ranger instead of 5w20. What could go wrong? Took my 2007 2.3L ford ranger in for an oil change, and they put 5W30 oil in it instead of the 5W20 that is shown in the book. Will this cause any problems, should i call them and have it changed/?
- Oil viscosity 10w30 vs 5w20? Been using 10w30 oil in 96 ford winstar and found out it should be 5w20 which am guessing is thinner is 10w30 too big a diff from 5w20 or is it ok its been 2yrs on 10w30
- Is it cheaper to buy a car that needs work? Read more? I want either a 1967 chevy impala or a 1972 ford pick up. Would it be cheaper to buy a car that needs some work or a car that doesn't need any work? My moms friend is a mechanic and he would do work for me cheaper than if i went to a regular mechanic and got work done.
- I had a oil change for my 2004 Ford focus.They used 5w-20 is that OK. In the past 5w30 was used. Is it OK? I had a oil change for my 2004 Ford focus. They used 5w-20 is that OK. In the past 5w30 was used. Is it OK? - 1
