Hybrid Oil Change Intervals (OCI)

[Hawkins12]

Question for the masses. I understand many will argue that my desire to do OCI's on short intervals for a new car may be excessive (and costly?); however, my desire has been to do short OCI's on brand new vehicles and then slowly extend after break in period. For example, I have a Lexus RX350 (non-hybrid) purchased brand new which I did my first OCI at 750, second at 1500 miles, third at 3000 miles, and now do them every 3000 miles going forward. I also send all my oil samples out for lab analysis --- not really because I can do anything about it but more out of interest. I consider this the "cost of a hobby" while perhaps showing some insight.

My question is regarding a recently purchased brand new Honda CRV Hybrid. I desire to do similar OCI's that I did with the Lexus above; however, the concept of Hybrids have me thinking. I know Hybrids use a mix of battery and gas depending on conditions; however, my question would be whether anyone in the group recommends doing them at longer intervals since presumably 1/4-1/3 of the time, the car is using battery power vs. gas power? Should one assume that 750 miles on a "gasoline engine" is similar to 750 miles on a hybrid engine? Thoughts on this would be helpful to understand.

We had a good discussion in a recent thread https://bobistheoilguy.com/forums/threads/are-hybrids-really-hard-on-oil.406049/

The Youtube video I don't think is worth watching and doesn't have any good arguments.

Normally the engine in a hybrid is doing much less work than a normal car, so it will wear the oil out slower. However, some folks pointed out that newer hybrids may not bring the engine up to temperature when they are driving short trips or around town. However, I don't think we have yet been presented with any actual evidence of this happening from used oil analysis.

If you are warming up your engine on most trips, I would expect the oil to last much longer (from a mileage point of view) than a normal car. 3,000 is indeed quite short of intervals for a modern gasoline engine and probably even more so for a hybrid.

Thanks for this. I did try to search around before posting but didn't run into this thread. I'll have to check it out.

I agree 3k OCI's are quite short in general, but I found it particular helpful with my Lexus. On the Lexus used oil analysis, I've been battling "high" fuel dilution close to 4-5%. Also, it's turbo charged so I think that further supports the 3k OCIs.

We have a separate vehicle where I was doing between 5-6k OCI's but then starting doing UOA and brought it down to 4k OCI's. It's been quite helpful from a numbers position. This vehicle is FREQUENT short trips (kid hauler) so sometimes it may only be used for 5-10 minutes at a time.

The Honda will have more mixed usage but will generally be used at least 30 min at a time. Long trips are likely going to be a minimum so I think I'll rely on the used oil analysis after 5-10k miles and tune the proper OCI. I suspect it'll settle around the 5k OCI but thats just a hypothesis.

Something to consider doing is basing your OCI on fuel consumed or on engine hours if that data is available. I have an older Toyota hybrid and it seems the ECU runs the engine a lot more when the engine is cold. It is more "reluctant" to use battery until the engine is warm and then it starts and stops the engine very often and maintains temps well. FWIW its a 2009 Camry with the 2.4L and has 230k miles on it. I just bought it as a fuel saving beater.

An example for a 20mpg car and a 5k OCI would be 250 gallons of fuel is 1 oil change. Keep doing oil analysis and see where that pans out. Direct injection and engine designs which shear oil faster will shorten oil life and that fuel/OCI ratio can be adjusted accordingly.

Valid point. I am new to the Hybrid game so I am still figuring it out which is being hurt by the fact that I don't actually drive this car (it's my wife's vehicle). I've been looking into a "higher quality" scantool (which I'll probably post here for recommendations later) which maybe can monitor this? I'll have to see.

Here's a used oil analysis from my turbocharged hybrid. It's a performance hybrid system so the gas engine runs a lot more than one would expect:

I don’t subscribe to the notion that hybrids are automatically “easier” on oil simply due to ICE run time. I have some used oil analysis in the UOA sub showing heavy fuel dilution in a hybrid. Doesn’t really matter if the ICE runs only a portion of the time when the oil is heavily contaminated with fuel.

Thanks for sharing. I starting sharing all mine on the Lexus but life took over I'll have to share with the Hybrid as well since there seems to be a lack of data out there. I had planned on using Pennzoil Ultra Platinum 0W-20 since I've been using that on the gas engines I have in the "fleet" however, I am bit intrigued by Mobil 1 Hybrid 0W-20. Not much data at all out there (Cant find a VOA).

Question on your Valvoline Restore and Protect. I am by no means an expert so forgive if this is ignorant. My understanding was that this was not a "use every OCI" type of oil. Seems to be your go-to here. Is my thinking wrong or are you trying something with this?

I am not aware of any official documentation stating Valvoline Restore and Protect is unsuitable for continued use?

Yea thats my concern with the hybrid is fuel dilution. As mentioned, I've been battling it with my Lexus which is not a hybrid but turbo charged. Seems to be consistently between 4-5%. I will get UOA on every oil change with the Hybrid and will post in the sub if I remember. I always enjoy people telling me its pointless getting used oil analysis on brand new engines/vehicles but as noted above, fun "cost of a hobby".

Fuel dilution isn't ideal, but I skeptical that it is as big of an issue as people are making it out to be. As long as the wear remains controlled, the fuel doesn't cause imminent issues.

I agree with this. What I haven't done (and am probably afraid to do) is run the oil longer to see. I can say my OCI's have kept my wear extremely low at 3k miles; however, it could also be seen as getting ahead of the problem before it becomes a problem.

Hybrids are best at saving fuel. Not extending oil drain intervals. I do 5,000 miles oil changes on the Sienna Hybrid.

I think this was something I read or heard somewhere (i feel like it was just recently as well -- maybe in a Lake Speed video?). Like I said, I am not knocking the product or anything -- it seems to do wonders -- but I thought the premise is that you don't consistently need that level of "Scrubbers" to break up deposits if you dont have deposits to break up. I believe the premise went on to say that it would perhaps be harsher on metal parts but of course that sounds counter-intuitive for an oil. I'll see if I can find it and repost if so.

Valvoline Restore and Protect is not an engine treatment. It’s a fully formulated API oil. Use it like any other.

I’d just follow the manufacturer’s OLM. No brainer.

Do you change the oil twice as often as Toyota specifies because you are worried about fuel dilution, or what?

Personally, having owned a high mileage toyota hybrid that had long OCIs and was still kicking when I sold it at around 265k miles, I'm skeptical of the need for shortening the OCIs. Just due to the well-established reputation for being some of the most reliable powertrains ever built by mankind and all that.

Their reputation was built off of a very different era of hybrid powertrains. No GDI, no turbos.

However, that era of “reliable” hybrid powertrains were serious oil burners. Most of them. Prius 1.5 and 1.8, Camry 2.4. Would more frequent oil changes have prevented this issue?

Couple reasons.

1) Toyota recommends 5,000 mile for severe service which I believe many people fall into more than they think. Instead of trying to track it, I just default to it as a practice.
2) Previous used oil analysis showed fuel diluted oil dropped to the low end of viscosity range or out of range.
3) Current oil change in the Sienna cost $20 after rebate. Not breaking the bank being conservative.

 

[JHZR2]

I’ve been running my accord hybrid by the computer, doing around 14k mile ocis, and it’s perfect. Minimal oil use over that duration, engine runs smooth and sufficiently powerful.

If it eases your brain to do it, then go have fun. But unless some objective issue found in UOA pops up, like fuel or moisture, just realize that you may be wasting time and resources just to appease yourself.
