Hi,

Just got back from my first service (A1) on my TL with only 6000 or so miles on it after a year. A1 popped up at 15% Oil Quality minder, no issues there.

My ambiguity now is that the cap on the TL specifies 5W-20; the dealer printout indicated 0W20. Going back in, I was assured that it was a computer issue in their system and that the service tech confirmed he had put in 5W-20.

Any thoughts? Do I need to worry? Does it really matter? What happens with a slightly thinner grade at startup?

it doesnt matter.
Honda switched to a 0w-20 for CAFE reasons. (Corporate Average Fuel Emissions)


a 0w and a 5w oil is basically the same at start up.

if anything, i did a lip kit for a 2012 tl 2 weeks ago.. i saw that the oil cap on the engine shows that it needed 0w-20 for some reason..

i found that very odd

CAFE reasons. CAFE.

Thanks, that's pretty much what I figured. If I get more OCD about it I'll head on over to bobistheoilguy.com and then stay up nights terrified over the thought I might not have the right oil.....

I double checked on bobistheoilguy and they said "basically a 0w and a 5w has the same weight at start up"

to put you at ease; Ive ran different oils in my 2006 TL.
ive ran M1 0w-40, M1 5w-30EP, and currently running Redline 5w-30 full synthetic.

No need to worry.

My dealership has always been using 0w20 full synthetic Honda engine oil in all 2012+ TL's that are being serviced there.

Although the oils may be the same, for some reason Acura does not recommend 0w-20 in the 3.7 engine.

The 3.5 in the 4G TL recommends 0-20

not mine.. my oil cap says 5w-20

This is the TL SH-AWD with the 3.7 engine; it is marked as needing 5W-20.

Called Acura Customer Relations, they checked it out and said it wasn't a problem. But I will remember to specify 5W-20 for all future changes, just because that's the recommendation.

Thanks for your help!

Might be 2012 and up then.

I believe it was '11 or '12 when Honda started changing cylinder liners to use some molybdenum, reducing friction and also switched to 0w.

Back in early 2012 when I had my 1st oil change done, I asked the oil weight question, and my dealership said it received a service bulletin from Honda saying that all 2012 TL's (FWD/AWD/3.5L/3.7L) were recommended to use 0w20 full synthetic oil.

This is for the Canadian dealerships. Don't know if it also applies to the US TL's ?

As others have said don't worry. I've used 0/20 and 5/20 interchangeably in my TL and wife's 09 Ody depending on availability with no issues.

at all the discrepancies in oil caps.
