0w20 more engine wear?

[Willys41]

When doing my first oil change on my jeep the first thing I noticed when replacing the filter there was NO oil in the filter housing. Not even oil dripping from the filter. IT WAS ALMOST DRY
All the oil in the housing and cooler had drained back to the pan
I said this is not right. What can I do
I had seen the Baxter put was skeptical
It wasn't until I walked into my local 4x4 shop and saw them installing one on a customers jeep
So I ask
Do they really work and any problems
Joe told me he has installed dozens and dozens with out any problems and they work great
I figured if he is installing on customers jeeps I would give it a try
I installed one first on my Rubicon and after a few day with NO more rattle rattle on start ups I installed one on my Willys
I have had the Baxter on for about a year with no problems and no more bone chilling rattle rattle on start ups
Its one of the cheapest mods I have done and glad I did

I am not bashing it; I did seriously consider it, but I decided against it for those reasons.

My question then is, where is the oil coming from? When I change my oil, I drain it hot, let it sit for an hour, refill with exactly 5 qts. and do the OM procedure waiting five minutes and I get a reading about 3/4-2/3 low on the dipstick. When I check it in the morning it's full.

BTW I've never had any rattle from the engine.

Let it set over night and then change the filter NO OIL IN THE HOUSING OR COOLER
Its not a hot start problem its a cold start problem
After sitting for an extended period of time the oil drains back to the pan

Yes, cold start... I was distracted.

Maybe it will help, just not sure how much as I think the wear at start up with a film of oil at the low rpms probably isn't significant, given the pressure builds very quickly, but as I said I would be hesitant due to the increased weight and leverage on the oil cooler assembly. If I was to do it I would relocate the oil filter. Having said that, if it reduced the rattle on your engine then it's probably helping.

 

[Willys41]

Yes the pressure build fast pushing all that trapped air in the filter housing and cooler though the oil galleys to the top of the motor
And that's a lot of air

My understanding is that most engine wear occurs on startup. If so, isn't 0w20 better than say 5w30 at minimizing wear because a thinner cold oil would be more important at reducing wear than a slightly thicker oil when fully warmed up?

 

[Willys41]

The difference 0w20 and 5w30 or 5w40 in minimal
Where you are gaining in 5w40 is when the motor is running hard and hot

To answer your first question, I am a bit skeptical that most engine wear occurs on startup, except in specific situations. It would depend on so many factors. On a well maintained engine, perhaps that's true, in which case if the engine was well designed it would last hundreds of thousands of miles until the start up wear caught up with it. However, that's not always the case. Dirt, grime, fuel, heat and viscosity breaking down would be a bigger factor. So selection of what oil to run, oil grade, choice of oil and air filters, OCI and heat management I think would be far more significant factors.

Regarding oil grade, since viscosity is temperature dependent, any grade can be any viscosity given the correct temperature for that grade. The bottle of 5w50 can be thinner sitting in a very hot car than a bottle of 0w20 in the same car on a cold morning. So it all depends on temps.

If you examine the circled values in the first chart below, you will see that all four grades have about the same viscosity and the difference is the ambient temperature, in this case about 5C difference per grade.

Once the engine is warmed up, the higher grade will be at the same viscosity as the lower grade 10-15 degrees C lower. (Second chart).

I have been looking put have not found any cam shaft or rocker issues with the Maserati 3.0 v6
This is the same motor as the jeep 3.6 put a 3.0
Does the Maserati 3.0 v6 have better cams and rockers. I don't know
Here are some differences
Maserati 3.0 v6 runs at 195 coolant temp
Maserati 3.0 v6 recommends 5w40 oil
Will making these changes to our 3.6 help the valve train survive. I don't know
If 5w40 oil is good enough for Maserati it will be good for my highly modified jeep with a 3.6

well said carbonsteel, thanks, maybe i will go 0w-40......

Nobody driving a Maserati would ever publicly post they had an issue. Second, they could care less if they did. Third, the rich probably never take their vehicles in for service, fourth, numbers, how many mazaratti vs FCA/stelantis, 1 to 100?

Unless they were so cheap they bought the V6.

 

[Willys41]

Then I guess the V-6 they are running in the Indy cars just not going to work
I will tell then they need to switch to a V-8

 

[azjl#3]

Right! V10 better

 

[roaniecowpony]

In the Maserati Ghibli, the base engine is the V6. The option is the V8.

I was browsing new and used prices. OMG I wouldn't want to take the hit on the depreciation on one of these. Even the new dealer prices are heavily discounted.

I had been running Pennzoil Platinum 0/20 from 22K-65K changing ever 5K. At the last oil change I switched to AmsOil 0/20.
