Maybe it's me, but I feel that I have read by a number of people that they run 5w30 instead of the recommended 5w20.

Why?

What are the benefits?

Thanks!

LoveMyTL-S

For me I just grabbed the wrong one. I'll be going back to 5W20 on this next oil change. But for some it may be a temperature thing. I think 5w30 has a greater temperature range.

5W20 is not readily availble everywhere, where it seems the rest of the world runs on 5W30.

5W30 runs a bit thicker... No real benefit to using it, unless in tropical climates. It may knock your gas milage down a bit, but certainly won't hurt anything.

Bearcat94

Some believe (including me) the increased viscosity gives better coating/film.

As kennedy mentioned the trade-off might be a little (very little?) loss in MPG.

Some have suggested that the car came out with 5W20 as the recommendation so that Acura/Honda could gain the little bit of MPG to help meet CAFE standards. Conspiracy Theory or fact? , but it sounds like something a big corp would do.

Spiritman

I only use 0W20 from AMSOIL. Also only their filter's. It's just the Best In The Biz. .
You can get the better coating/film you are looking for just by switching to "The Best" = AMSOIL!

5W30 oil due to the thickness difference can probably quiet valvetrain ticking a little also.

I use 10w30 is that ok i have been using it since i bought the car?

paliknight

which number determines viscosity

JwongTLS

I ran 5w30 one time by accident, and I guess u can feel the oil a little bit thicker (inthe head ).

If u like to push your car, you should probably go 5w30. Because of the thicker oil, it can withstand greater heat and better lube at the high RPMs.

The car just dont feel right though?

Use 5-20 to get the maximum benefit out of quick lubrication at startup and the proper lubrication while driving after warm up. The thicker oil not only causes more resistance, it also will make the engine run hotter because of that resistance which is proof with the decrease in fuel mileage as the engine works harder. Having said that, nobody will ever notice that difference, unless in a controlled laboratory environment.

Both. To make it simple, the first number is the viscosity when cold, last is the viscosity when hot.

you have a reccomended grade for oil (5W 30) because it provides the best overall protection for your motor. And it probably helps keep the motor quiet as well.

Our cars are recommended for 5W-20 oil. I switched to 5W-30 lately and got a 1-3 MPG loss on highway and I drive on the highway a lot.

J-STEELE

I just bring my car in to service and let them deal with it! haha... lazy ass I know.

PEACE!

Friss04TL

I would never hand it off to a shop!!!!! So what is the final say 5-20 or 5-30

yiujai86

Don't you switch to 5w-30 as the engine gets older as in having more miles on it?

TheChamp531

5W-20 Extended Performance Mobil 1, enough said.

LaCostaRacer

As others have said 5W-20 is recommended by Honda but most likely only for a little increase in gas mileage. I use 5W-30 when I can't get 5W-20. You also have a better selection of brands in the 5W-30 range as well.

I 'm ok with the 5W-30 in the Summer due to higher temperatures and just did an oil change using 5W-30 a couple of weeks ago. I use the 20 in fall/winter. I don't see any measurable difference in mileage so that's a mute point for me.

Spiritman

Your almost there! If you want to settle for 2nd best. Your OK!
>
But AMSOIL is still the top banana! Although Mobil 1 Extended Performance is my 2nd choice. But I would NEVER use 5 W 30. Ask Acura they will tell you. Our car is MADE for 5 W 20. The holes in the engine are just the right size for that viscosity.

OK, I'm done now.....

• API SM/CF, SL, SJ. . .
• ILSAC GF-4, 3. . .
• ACEA A1/B1

Is that what your looking for?

Yup, that's what they say, but not ALL Amsoil products are API certified. Another falsehood from Amsoil as they lead you to believe that all their products are certified by the verbiage on their website. Check the API Certification listings and then come on back.

It's like if you need a nurse, I can supply one that's not certified but can do the job, you can take my word on that!

You'll be fine running 5w30. My Accord has the same 5w20 recommendation that most Honda/Acuras have had for years, and it still runs fine past 150k.

chuanger

On my Accord, I once switched to 10w30 and I saw a noticable decrease in my gas mileage. Ever since then, i've only use factory recommended oil weight for all my cars.

Wish I Had A TL

I would rather change the oil every 6K miles with PP 5-20, then every 12K miles with Amsoil. Imho.

01tl4tl

Oil numbers:
the first is the viscosity or abilty to flow as measuired at 32 degrees F
W stands for Winter..the oil has additives that ALLOW it to function AS IF it were a 5 when at F freezing temp
The second number say 20 or 30 is the actual viscosity of the oil as measured at 200F thats normal oil operating temp
Even that number is fake as additives make it work as if it were a ..at that temp

FACT: Acura went to 20 on gen3 for the .5-1mpg increase for the purpose of meeting CAFE standards which are an average across the fleet of cars they make
Gen 2 uses -30 and it dooes offer slightly more protection for all the metal parts thrashing together thousands of times per minute

You can run either, not based on engine age. The book allows both 20 and 30,
the 0 or 5 part doesnt even come into play for most of the country this time of year

In really warm summer temps the 30 offers more protection to the engine

...Might as well go with what is recommended...5w20.

TheChamp531

iTrader: (3)

10w30 is a big difference than 5w20 or 5w30

01tl4tl

thats really funny
How many of you live where the overnight temps are sub 32F?
Thats the ONLY time the oil ACTS like its a 5
Otherwise its as stated on the higher number

JETSPD1477

i took a lubrication class certified by valvoline way back in my auto days. from what i can remember, is that all viscosities lubricate at the same level, and the viscosity ratings are a common misnomer for lubrication and protection. the ratings that are the most important are the API ratings... period. any motor oil with the same api ratings will offer the same amount of lubrication, from 0w20 on up to straight 50 weight. The question is how readily you would want motor oil to flow. the higher the weight the slower it moves/pumps. sure a higher weight will stay in place longer, but what about replinishment? the differences between 20 and 30 weight is mute, and both will work fine. i figured i'd toss in my two cents.

tehloxely

Walmart by me stocks Synthetic (and non) 5W-20 of all shapes and colors as of recently.

Spiritman

I live in Minnesota. We can see -35 below zero or worse. I remember a cold winter night when the wind chill factor (I know it not a big deal on metal, just flesh) of > -100 below zero!!! Man thats cold! Try a straight weight oil in that! I was using Amsoil then as well. I was ice fishing that night. I started my car (Saab) every other hour! It was stiff even at that......

DJANZ07

I think when you ask for mobil 1 at the dealer ship they put in 5w-30 in New york, but I'm not too sure, its runs smooth as hell though with some shell v-power you'll have quicker acceleration response and better gas mileage!!!

ross7778

I've been using Mobil1 5w-20 but plan on switching to 5w-30 as Costco sells it for $32 a case. And for May they have a coupon for $10 off.

Not that it matters, but I had a 2G TL before we got our 3G TL... Our 2G TL also recommended 5w-20. I know, becuase at the time it was a pain in the arse to find 5w-20, since I always bought my 5w-30 by the 5 quart jugs, and nobody had 5w-20 in big jugs until after I got the 3G TL. (at least around here anyways)

My 01 civic required 5w20 also and it was hard to get back then. ( I think i was using penzoil backthen)
on the TL i run 20 in the winter and 30 in the summer

Amsoil 0W-30. Change oil every 25,000 miles even though its guaranteed for 35,000 miles. I've also seen a 3-4mph increase using this stuff which didn't surprise me because the representative told me I'd see it before I bought it anyways.

Wow, never knew you could keep oil in for that long..

Elegant TYPE S

iTrader: (2)

They tell you .. that you dont even have to change it at 35,000 miles. They want you to change the filter at 25,000 miles and then do a oil analysis at 35,000 miles. Most cars running their oil can last well over 40 to 50,000 miles. Me I change it at 25,000 when I change the filter.. peace of mind.
