Mobil 1 vs Amsoil

[Poper09]

I am struggling to choose between Mobil One 0W-20 Extended Protection and Amsoil OE, XL, or SS for my 2019 Acura RDX Turbo with 30k miles on it. I change my oil every 5k miles.

I believe both are good oils but not sure if Amsoil is mostly marketing or legit?

Any help/suggestions would be helpful...
Thanks

@ 5k OCI your engine won't know the difference but your wallet may.

You want an opinion on how they rank?
Amsoil SS
Mobil 1 EP
Don’t bother with the others bcs they are no better than #2 above
I do agree 5k is short for the two oils above …
Does that engine dilute the oil with fuel ?

M1 it’s readily available at around $26 at Wally World. Or for any 5k mile oci QSUP or Valvoline EP

I have no reason to believe the engine dilutes oil with fuel. How would I know?

Other members, run your own UOA’s, do some searches

I have the same car and here is oil analysis

kirkland 5w-30, 3800 miles, Acura RDX 2020

glad I went up in viscosity, 5w-30 now looks lower than 0w-20 thanks to all the fuel dilution. Car get 70% highway miles. Oil changed at 50% of MID.

Your best bet is to use 5w-30 and change oil every 3-4k miles; this engine is a fuel diluter. The oil brand does not matter so much for short OCI.
Plenty of data on your engine in Used Oil analysis forum.

Both are too rich and unnecessary for my vehicles so I cannot make a recommendation.

Looks like a member has posted that they do …

IMO (strictly an opinion), the Amsoil product line is going to be more of the upper-end, boutique stuff. Nothing wrong with M1 at all; also good stuff, but more mainstream.

The real distinction here is that both of them are overkill for a 5k mile OCI. Honestly, ST syn would be perfectly suited for such a short duration, or whatever decent quality, properly spec'd lube on sale for that matter. You'll save money and your engine is unlikely to know the difference for such a short OCI.

How many miles per year are you driving?

12k to 13k per year

Both are formulated for long drains but absent significant fuel dilution at 5k miles intervals you're wasting your money unless the price is good.

Here we go............ Both are good oils, use what you think is best.

Will Acura correct the fuel dilution problem?

 

[tolian21]

I bought Kirkland on sale, comes out to be $15 for 5qt.

 

[tolian21]

Will Acura correct the fuel dilution problem?

Not for the current engine, maybe for next gen

Will Acura correct the fuel dilution problem?

No, change your oil every 3-4k. I would use Quaker State 5w30, Full syn or Ult Pro would be great choices. Good luck just change it often

Also, to make you feel better, Mexican owner Manual for 2019 RDX lists 5w-30 and 0w-30 as acceptable viscosity.
