Recently got a hybrid car. In the USA they spec 0w20 and overseas they spec 5w30.

Im not from the US just in case.
Would 0w20 really flow that much better from the constant start/stops of a hybrid engine or the 5w30 would provide better protection?

Ambient temp never gets below 23-24c which is around 73f-75f

Just looking for opinions, we are in bitog afterall
 
It's not about flow, it's about cranking and pumpability. If the engine cranks the oil will flow. The winter rating is what is important there anyway, and at the temperatures you list an oil with a 20W winter rating would be acceptable.

Here are a few previous threads on this extremely popular topic. If you look around you will find at least 50 more that touch on the subject, some are pretty long and epic with extensive dead-horse beating. The first one below is pretty specific to your question.

Thread '5W-30 instead of 0W-20 for 2016 Toyota Camry 2.5 Hybrid'

0W-20 is the label on the oil cap in 2016 Toyota Camry Hybrid

I went to a parts shop to buy oil and the seller said it is better to use 5W-30 for hot weather, he said 5W-30 will protect the engine better than 0W-20 for high temperatures summer.

Is it true? Thanks

Thread 'Designed for 0w-20 but 5w-30 is recommended?'

I recently bought a 23 Colorado ZR2 which has the 2.7L Turbo engine and did a bit of research on the engine before purchase. So far I'm impressed with the engine.

I was watching a YT video of an interview with one of the GM engineers that developed the engine. One of the comments he made was that the engine was designed to run on 0w-20 oil but they recommend 5w-30 for increased protection and longevity. I thought that was interesting and it goes along with my general thoughts on oil viscosity.

Thread '0W-20 vs 5W-30 synthetics in cold temps'

I have two jugs in my stash right now.

One SuperTech 0W-20 HM, and one Pennzoil Platinum 5W-30 HM.

Engine is a Honda 3.5 V6. Burns a bit of oil, maybe 6/10ths of a quart every 3,000 miles. Car calls for 5W-20.

Mileage is approaching 150,000. I'd like to start running 30 weights for film strength, but with the cold weather almost here (coldest mornings for me are about -10 degrees F. Not crazy cold, but still cold).

That said, I don't want to run the 5W-30 weight in the winter if it's going to induce extra wear as cold start-up over the 0W-20. At those temps though, is there even really...

Thread '0w20 vs 5w30?'

Hey guys,

Hey guys I have a 2020 Accord 2.0t the factory calls for 0w20 but I was wondering if 5w30 might be a better option? It’s also tuned for flex fuel and has a Civic Type R Turbo swap estimated power output now is around 360-380 horsepower. I was thinking tobuse 5w30 when racing it and then use 0w20 all the other times and in the winter time? Or just stick to 5w30 all year round.

I don’t run it on E85 frequently due to not many gas stations having it in my area so most of the time I’m on 93 octane. Should I stick to the factory 0w20 or switch to 5w30 for more protection ?

Thread 'Any reason I can't use 5W30 short term for engine calling for 0W20?'

Putting a first Gen Honda Insight back on the road that's been sitting 6 years and will be doing two oil changes a few hundred miles apart to clean the engine internally. Any reason I shouldn't use Mobil 1 5W30 that I got during the Walmart clearance for 10 cents a quart for the first change before using the correct 0W20 on the next one?

Thread 'Pennzoil says 0w-20 or 5w-30'

So I used the oil chat selector by clicking the banner ad for Pennzoil. The bot asked if it was high mileage I said yes. It said the best option is ow-20 high mileage Platinum and also suggested Platinum 5w-30.

So what’s the difference between these two oils and which should I use

The previous owner used HM oil, so maybe I should continue that

Thread 'Don't use 0w20/0w30 in place of 5w20/Xw30??'

Some where in one of the topics in the BITOG forums I remember seeing something about 0W oils in place of 5/10w Oils. And not for the life of me I can't find it again.

Anyway, I thought I remembered reading something along the lines of people now preferring to stick with a 5w over 0w oils. This is by no means a quote of anyone, but I remember something along the lines of 0w oils either having a higher NOACK percentage, or a higher break down rate which leads to high deposit and sludge build up on engines due to the higher viscosity spread? I apologize for my ignorance here, but my memory...

Thread 'Is the Toyota 0w-20 recommendation for CAFE?'

Is 5w-30 actually better for longevity? I ask because I noticed that the recommendations for the 3.5L 2GR-FE V6 used to be 5w-30 in prior years and now it is 0w-20.

I also noticed that in Australia, the current recommendation is still 5w-30.

So does anyone have an opinion about whether 5w-30 is still better for longevity?

Thread 'From 0w20 to 5w30 lost 4-5mpg??'

Hi fellas, I for one have never been a proponent of these 0w20 oils for a rise in mpg that is noticeable at least and not the manufacturers .00000001% increase study.

But I've just witnessed something with my '13 Sentra that I think may have me thinking a lil differently... It came from Nissan with FF 0w20 from what I'm told, I just had it changed at my dealer at 3750 miles as part of my free maintenance (normally ALWAYS change my own oil, but hey, its free) so I ask the service adviser what brand they use and what weight they would use and he quickly said "we don't have the 0w20 here, so...

Thread '0W20 Myth or Truth'

I head somewhere that all the Honda's, Toyota's, + Some other vehicles that were initially spec'd for 5w20 can safely move to 0w20. Some dealerships even recommend it.

I recently moved to a full synthetic high mileage 0w20 in my 05' Odyssey which originally calls for 5w20 and has been running great and not burning any at all.

Thoughts?

Thread '2015 Skyactiv 0w20 vs 5w30 MPG'

Haven't noticed much if any of a difference at all in terms of fuel economy. In fact I was telling The Critic the other day I was able to get 41.8 mpg on the 5w30 EP oil, cruising at 80 mph too.

Really impressed with this car and the Skyactive engine. I now have 21,300 miles on it. I still have to send off a UOA of M1 0w20 with 8,000 miles on it from 2 oil changes ago.

I'll probably switch back to 0w20 for the winter, or maybe go with AFE 0w30. The HT/HS difference between the 20 and 30 grade is a small 11%.

Thread '0W 20 vs 5W 30 in a 2017 Mazda 3'

I daily a 2017 Mazda 3 iSport hatchback. It is time for another oil change and I brain farted on what weight oil so I pulled out the owners manual (online) and according to it I should use 0W20 in the USA, Canada and Puerto Rico but outside of those areas I should use 5W30. I can only imagine that is due to fuel economy standards. Any other thoughts?

Thread '5W30 In ‘20 Corolla 1.8L ?'

The ‘20 Corolla 1.8L non-turbo owners manual states to use 0W 20 oil with no other oil weight options listed . Are there any special engine requirements (VVT , etc.) for the ‘20 Corolla 1.8L that would prevent a 5W30 synthetic oil being used ?

Thread 'Hypothetical 0w20 vs 5w20 vs 5w30 question'

Opinions wanted

I know any decent brand full synthetic will suffice, but I want to know: given the same brand and line of oil, will one provide marginally better protection from wear, shear, heat dissipation or any other measure?

The specific engines I’m asking about are a JLR AJ133 and a honda K24
Both have timing chains. Both list 5w20 in the owners manual. Both would get filled with 0w20 at their respective dealerships for an oil change. I’m not sure about Honda but the official recommendation from JLR for my engine is now 0w20.
But I’m pretty sure the 0w20 is for fuel economy...

Thread 'Long Term 5w-30 use in Honda 1.5t'

2022 Civic Sport Touring 1.5t currently running 0w-20 as the manual specifies and filling up with Top Tier 87 Octane but I've heard this L15B7 and variants do show 5w-30 in owners manuals in other parts of the world. However there may be other differences such as fuel which is more "potent" outside of the US which may be a factor in this (I don't know if it is or not but just thinking)

I'd like to keep the car for a long time as I'm already over having a car payment, curious if anyone has used 5w-30 long term in these engines and how they have been holding up. I don't have many...

I bought 0w20 preemptively. Now i have 2 5qt jugs of such oil.
I will probably use the 0w20 in the beater and get some 5w30 for the newer car.

No since almost all start stop cars are not programmed to do that until they get to a certain temperature so start stop flow isn't a concern and even if it was it's minimum. I'd use 5w-30.

That has not been my experience with hybrids specifically. After an oil change on the Sienna Hybrid I always press the gas pedal while in park to get the ICE to start so I can check for leaks. It will usually stay on for 30 seconds to a minute and then shut off. Also, while driving, I’ve seen it shut off within a less than 30 seconds after starting. Oil temp isn’t a factor for cycling off from what I have seen. Non hybrids are a different story.
 
There is so much thermal management on these cars now, well beyond your daddys old Chevy 1500. They heat up a lot quicker, keep the heat in better, release the heat better, have double cooling systems (inverter) and oftentimes electric motors driving the accessories.

Its the same engine at the root so use what you want, but these engines seem to last forever and forever on any kind of oil. I run 0w-20 in mine and I dont loose a minute of sleep thinking about it.

Any API cert 5w30 and sleep well. We used 5w30 in all our hybrids at work also.
