I will be bring my car to the track next Friday and it is about time for an oil change

my mech recommends me to do the Motul 8100 5W-40 instead of 5W-30 or 5W-20, he said it works better in hot temp and esp on the race track, and it will be much better.

this year is extremely hot and i guess it will work well

I will give it a try anyways, but is there anyone using 5W-40 or higher?

 

no, 5w30 is going to be fine, 40 weight is going to be thicker and rob you of power

 

keep in mind you can mix 5w-30 & 5w-40, what i do during the summer only is mix 2 0r 3 quarts of 5w-40 at oil change.

 

Is it true that as your car gets old (more mileage), you need to get thicker oil?

 

thats not needed. 5w30 is more than adiquit. thats all i run on track days and autoxing. my car idles all day long on 5w30.

and progz No. im at 185k on 5w30. not a drop ever burned or higher needed.

 

fsttyms, are you using the new extended mobil 1 ? I think I read a post by you that you were going to try it. Any comments ?
TIA

 

yes im running it now at 15k intervals. had it tested at just under 15k and it had a TBN of 3.2 which is VERY good for that mileage

 

Thanks fsttyms1 !
So this is the Mobil 1 Extended Performance (5w-30) with the yellow cap. And I'm guessing you sent it to Blackstone Labs.
samkws, sry for the threadjack

 

yes and yes

 

are you chaning your filter intervals as well? or are you just changing them at 15k too? thx

 

15k also

 

nevermind, i hooked up with somebody at Acura dealer and i will do Amsoil 5W-30 instead

got a gd deal

 

i will switch so synthetic next oil change,wich one should i use and would the regular Acura filter do?

 

i prefer mobil 1 and any extended use filter will suffice

 

Thanx Man ! I think I'm goin' try it. I'm due.

 

just go to blackstone's website and request a sample kit. and when ever you do send it in check the little box for teh tbn test

 

5w20 is hard to find in Lincoln, NE. My 1st change I found some Mobil 1, 0w20 at Walmart. They don't stock it here anymore. My second change I ended up ordering some Redline 5w20.
I thought that should be ok too.

 

5w30 is ok too. the only reason honda went to the 5w20 was to help meet CAFE standards

 

I actually have the kit. I got it a few years ago when I read your post about them. Just haven't gotten around to it.

 

That's very interesting. I didn't know that.

I would assume that Honda wouldn't have to try too hard to meet the CAFE standards.

 

actually hondas really arent that efficant (insert tl gas mileage here)

 

But they aren't inefficient, either. I think they are definitely above industry average.

 

i would have to say GM is probably one of the best. every one i know with a GM car gets great mileage. hell my dads caddy deville with a V8 northstar gets 28-30mpg at 80

 

Their trucks are killing the CAFE, though. My dad's XL Denali is, if I remember right, rated at 13 mpg in the city.

 

BRICK IN THE WIND

but my last silverado got alot better than my neighbors f150

 

GM trucks > Ford trucks

I can't remember the cD on my dad's car, but I believe the Hummer H2's cD is .43... like you said, brick in the wind.

 

hahahaha!

 

fsttyms1, which brands of extended filters do you use/recommend.

I'm currently running Amsoil series 2000 0w-30 with an Amsoil filter on 10k changes.
