Motor oil for Turbo going uphill

[Carguy21]

That engine only holds 3.7 qts.

But the market is moving on making mid-size SUVs with small 4 cyl engines like the new CX-9 with a 2.5T engine, but they recommend 5W-30.

Here we get on the 5W-30 range M1 and PP also the Motul X-clean 5W-40 which carries Porsche A40 and BMW LL-04 is widely available.

Do you thing those tiny engines on large SUVs can last up to 5 years without any mayor issues?

0w-20 is used for fuel economy in the US.

IMO, in a tropical climate like yours, I would not hesitate to run the 5w-30 or even xw-40.
When I went to the tropical part of Asia with a lot of small SUV, they even run 15w-50 oil.
The cars last a long time over there.
My dad used to own a Corolla for 20 years, the body gave up with rust.

10w30 all year

It's interesting That the earliest proponent of 5W-20, Ford, is now saying to use 5W-30 Ford spec'd oil in their DI turbo Ecoboost engines. "Maybe" they realize that these types of engine are harsher on oil versus non turbo port injected engines. I've used 0/5W-20 oils in my Ford Modular 4.6 V-8's with real good results, though I do no serious hauling. My wife's new 2017 EB 2.3 Explorer requires 0/5W-30 meeting Ford specs and my 1996 2.0L Zetec was originally spec'd for 5W-30 and that's what it has had all it's life and is super clean under the valve cover and uses no real amount of oil in a 8,000+ mile OCI. Maybe Honda knows something Ford doesn't know about DI turbo engines

Castrol EDGE 0W-30. PAO based, high heat tolerance. And having the LL-01 certification ensures it has been through the rigorous BMW turbo test.

I would personally want to use a 5W-30 or 10W-30 but would stick with a manual-recommended weight while the engine is under warranty.

 

[earthbound]

go ahead and keep that ff in for the allotted time Honda recommends by using the olm, and see what happens with that oil.

Yes. A 30 weight oil for the constant heat, synthetic to better resist that heat. 1 hour under heavy load is a lot.


1 hour under load is a lot??? I think a synthetic oil will perform as it should without fear of "not handling the heat" !

 

[WobblyElvis]

Perhaps extra cooling is the answer. Optional oil cooler?

what about going down hill?

That would be a brake fluid discussion

Honda was one of the first to use 0W-20 oil(1st gen Insight and Civic Hybrid), and I do have faith that they designed the engine around 0W-20, although there are reports of fuel dilution with that turbo engine. Honda does have a spec for turbo-approved oils, HTO-06 that must be met for them to approve an oil.

Run the stoutest 0W-20 and see what the Maintenance Minder returns for mileage before you see A/B1. If warranty is no object and if it doesn't fall below 50*, you could try a 0W-30/0W-40 high HTHS Euro oil. There isn't a 0W-20 that meets HTO-06... yet.

If the manufacturer recommends it, they have tested it. Sure, the engine may only go 400K on 0w-20 instead of 450K on 15w40 or 20w-50.


A more appropriate comparison has been brought to the table in other threads by SR5...

GM, with the turbo 1.4 in the states specify a Dexos 1 in an ILSAC grade...in Oz, they specify Dexos 2....HTHS greater than 3.5.

I fail to see a single (gas) application where a euro oil (LL-01, A40, 229.5) would be ill-advised. To me they are the platinum-standard of passenger car motor oil, focusing more on wear protection and long-life versus fuel efficiency.

10w-30 synthetic. M1 makes a good one, so do penzoil and Valvoline

If you can't find that pick a 15w-40 HDEO. You want to maintain viscosity in that motor when the oil hits 300F halfway up that hill. Synthetics preferred

Yes, I heard it ..... that manufacturers know best.
I would pick a shear stable xW30/xW40 for this application.
JMHO.

When did cafe mandate 0w-20?

IDK.
Credit to Shannow,I do know 5W20 is dated 2000.

5w30 or 10w30 synthetic meeting the Honda HTO-06 standard.
Mobil 1 5w30 meets HTO-06...

 

[JoelB]

Run the 0w-20 for 1 oci of this usage and get a UOA done. It will give you a rough idea of what to do next.

 

[dblshock]

I believe in order to meet Honda/Acura HTO-06 it must first be 5W-30 grade oil.
