Wrong grade oil

[RangerDownUnder]

Alright, I screwed up royally today. I changed the oil in my 2004 HZJ105 and realized afterward that I used the wrong oil. I put in semi synthetic 15W-40 API SM instead of API CF-4 (or CH-4, whatever the new equivalent is). I did a test drive of maybe 5 minutes or less once I changed it. I know it was a boneheaded move and I need to pay more attention to what's written on the bottle when doing this again.

So I'm going to replace the oil with the correct grade and put a new filter on. Since I didn't drive it for very long, I'm hoping just changing it will mean no lasting damage but is there anything else I need to do?

Thanks for the help.

No damage done. The SM oil is still a high grade motor oil, it would just have a different additive package to a Diesel engine oil. A 1hz will cope with a lot worse.

I seriously doubt that any significant damage would have resulted from less than 5 min.

You are worried about that? It wont make any difference what so ever and leave the oil filter on if its new. Relax, the 1HZ are tough old beasts.
Some oils like these are used in light duty diesels according Penrite

Thanks. Good to know it's not really a big deal. The oil filter was new so I think I will leave it to save a few bucks and not make another mess. I'm still new at doing my own vehicle maintenance so I freaked a little when I realized what I had done.

No problem at all. Look up the data sheet on that oil and you'll find it's applicable C rating even if it's not on the bottle.

It would be a waste of time, money and good oil to change it before it's due.

D - All of the above.

The oil you've just put in would be a lot better than the dirty oil you just took out.

According to the chart you are right assuming it is the wrong oil but that is just theory, in real life there is no problem I think, but all the different ratings are confusing: start a discussion about the right birfield grease viscosity

gasoline engines: SM CURRENT
For 2010 and older automotive engine

diesel engines: CH-4 CURRENT
Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards.
CH-4 oils are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight.
Can be used in place of CD, CE, CF-4, and CG-4 oils.

Diesel engine: CF-4 OBSOLETE
Introduced in 1990. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CD and CE oils

It depends on what you used. For example:

Mobil Delvac MX™ ESP 15W-40 is an extra high performance diesel engine oil that helps extend engine life in the most severe on and off-highway applications while delivering outstanding performance in modern, high-output, low-emission engines including those with Exhaust Gas Recirculation (EGR) and Aftertreatment Systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). Fully backwards compatible, Mobil Delvac MX ESP 15W-40 will also deliver the same exceptional performance in older conventional engines. As a result, it meets or exceeds the requirements of the API CJ-4, CI-4 PLUS and CH-4 service categories as well as key Original Equipment Manufacturer (OEM) requirements.

Mobil Delvac MX ESP 15W-40 is the result of extensive cooperative development work with major OEMs and is recommended by ExxonMobil for use in a wide range of heavy duty applications and operating environments found in the trucking, mining, construction, quarrying, and agricultural industries. This product provides outstanding protection in the most demanding diesel engines of Caterpillar, Cummins, Detroit, Mack, Mercedes Benz, Renault, MAN, Navistar, Volvo, and others. Mobil Delvac MX ESP 15W-40 also meets or exceeds the requirements of the API SN / SM / SL specification for gasoline engines and mixed fleets.

I had used Nulon semi synthetic 15W-40 modern everyday and I called Nulon to ask if it did in fact have a API C rating that wasn't on the bottle. The tech advisor said that the previous iteration of that oil did have an API CF rating in addition to an API SL rating but the new product only has the API SM. It probably would have been fine if I left it but I figured better to just replace it with a CF-rated oil to be safe (although I didn't change the oil filter).

That means they didn't bother testing that oil to a C (diesel) spec as well as S (spark) spec. There's no doubt it would pass but they simply didn't collect the info.

Comparing it to other oils with similar S ratings would give you an indication of the C rating it might acheive.
