How Stout Is Honda's HTO-6 Spec?

[Red91]

In comparison to say, dexos1 or a current ACEA spec, how does Honda's HTO-6 measure? It seems like I remember reading it was for their turbo/high performance engines. I'm going to run Quaker State Ultimate Durability 5w30 in my new Cruze, and I noticed it meets that spec. Just curious.

I believe it is a stable high temperature spec. It is likely that many well known synthetics will meet the spec in the 5w30 grade even if it is not listed on the bottle.

Dexos1 is a much newer spec, however i am unsure in which areas their performance parameters are similar if they are at all.

Honda like it as it was designed for use in the vehicles it is specified for.

Use in non spec'd vehciles could create cause for concern.

How would the HTO-6 spec oil used in non- spec'd vehicle cause any problems? I think this a good spec for any engine since it protects against HT deposits. The spec may be history now because of newer specs. Ed

Not even close. Mobil 1 5w30 is on of the most popular grade/brands in the U.S and it can certainly be used in any application that prefers the 5w30 grade.

If you are referring to the additive pack, HTHS, or KV, the HTO-06 spec is not "stout". Probably a good oil for your Cruze though.

It was discussed here a while ago and I recall it being a rather stout high temp spec. Ironically, that spec listed on a bottle of oil for Honda probably sells a lot more oil for people driving turbos of other makes as Honda has only one turbo charged engine in North American IIRC....

Arrivederci !!

Yeah I think they only imported like 10k to 20K examples of this turbo 2.3L engine into the US market. It's kind of interesting to have an oil specification, and people talking about it, for one engine that was imported in such low numbers that most people have never even seen or driven a car with this engine in it.

What?!? It's a test regimen for turbo use. Plenty of fine oils hold that plus many other specs. No issues.

The pedantic response is that it might not do well in VW502, 505, 507, LL-01 etc apps.

Everyone, including myself, knows that we are all referring to it doing well in regular SL/M/N and Dexos I applications.

HTO-06 is very limited to high temperature deposit performance only. dexos1 and ACEA specs are much more comprehensive, although any dexos1 oil is also SN-GF5 too. For your GM Cruze and any gasoline engine, dexos1 is actually a great spec, although the Euro specs like MB229.5 and A40 are even tougher specs to meet for cars/suvs etc. that require Euro specs.

Finally caught on here. Not being pedantic its when making broad statements please qualify these.

Not everyone has been on this site or those that surf this site for as long as Eddie or as long as Simple_G etc and can be misleading where the knowledge base not as strong.

BITOG is quoted as fact by some as the ORCALE for knowledge and some opinions become skewed as facts.

IMO Simple_G not everyone interprets "any engine" as excluding the ones you mentioned. Anyway there more important things in life "like watching time go by........"

La stella vista.

 

[Red91]

I should be more specific; is it a rather tough standard to pass? If an engine oil meets or exceeds the spec, is that establishing the oil itself as tough or "stout"?

HTO-6 was a high temperature deposit cert, much like GM 4718M.
Honda was probably concerned about coking in the rare turbo Acura CUV while GM was concerned about oil temperatures in tracked Corvettes, since no factory oil cooler was fitted.
I would be confident that any name-brand synthetic labeled oil you'll find on the shelf would be capable of passing the lab tests to meet HTO-6, GM4718M or dexos 1.
It gets iffier with oils not labeled as synthetic, although many of those would probably be capable as well.
