is using this oil ok?

[MyBloodRunsBlue]

well i was seeing on the oil topic thread that most are using 5w20...when i did my oil change 4000 miles ago, my buddies told me i should put 10w30 in my motor...as of right now i have royal purple 10w30 as my oil...my question is, should i change it to 5w20 or is 10w30 fine for my car?? i have a 5spd 2001 GT with 70,000 miles on it...

Thanks for any input

Have no clue about 10w30 oil but I cam changing my oil sunday with mobli 1 5w30.
I have always used mobil 1 5w20 but I am going little heavy weight cause vegas getting real hot now a days

I think the next time you change the oil, go with either 5w20 or 5w30.

No one ever uses 10W that is too thick for cold starts especially in the winter. You should be ok but change it out before it gets cold. Even better change it right away.

Only if the temps are below -20 would a 5w oil provide a benefit over 10w. Otherwise if you're temps don't get below freezing I wouldn't worry much.

Ford recommends 5W20 for my '03, but I run 10w30 all year long. 20 weight oil is way too thin for our hot running engines. Ford switched their recommended oil weight a couple years ago so they could better meet C.A.F.E. restrictions. Whether you live in the North and run 5W30 or live in the deep South and run 10W30, the important thing is that you use a 30 weight oil!

Well, I have seen a lot of people going the opposite way and running 0W oils.

They must live in Alaska then cause there's no need for an oil that thin.

Everyone does realize that the "W" in 5W30 means winter, right?

Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).

Oils meeting the SAE's low temperature requirements have a "W" after the viscosity rating (example: 10W), and oils that meet the high ratings have no letter (example SAE 30). An oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by the length of time it takes to flow out of the hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.

Engines need oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils. These oils meet SAE specifications for the low temperature requirements of a light oil and the high temperature requirements of a heavy oil. You will hear them referred to as multi-viscosity, all-season and all-weather oils. An example is a 10W-30 which is commonly found in stores. When choosing oil, always follow the manufacturer's recommendation.

i use 10w30 all the time, one time i mixed 5w30 and 10w30 accidently, personally i dont think it really matters unless you live in alaska

That doesn't explain why using a 0w oil versus a 5w or 10w would provide any additional benefits in temperatures at -20 degrees or above?

I run 5w-30 in the summer and 5w-20 in the winter on all my cars, and they all specify 5w-20. I'm old school when it comes to care care, personal preference I guess.

 

[Uncle Meat]

never mind....

 

[Kilgore Trout]

 

[Uncle Meat]

I was going to explain to 03gtdrkpny why there was really no reason to run a 5w20 in the winter and a 5w30 in the summer. If anything he should just run 5w30 year round. Then I thought about all the typing I'd have to do to explain why and well... I'm just too lazy to type it out.

i live in alabama and during winter the coldest it gets is probably low 40s sometimes 30s....but summertime it's mid 90s so is 10w30 good?

It wouldn't matter anyways, I'm stubborn as a boar.

I actually know a few guys that run Rotella T in their DD's and draggers believe it or not and swear by the stuff.

Personally, I run 5W-20 Mobil 1.

Yup. No need for 5w here in 'Bama.
