Going thicker to reduce consumption

[SilverFusion2010]

Ford Fusion, 3.0L V6, 177k miles. Daily driver with mixed city/hwy about 50/50. Currently running Mobil 1 Advanced Fuel Economy 0w-20. Car has always burned some oil, usually about a quart in 6k miles. I’ve been topping off every couple thousand miles and I think it’s started burning a bit more. Going to go thicker to see how it affects consumption. No smoke or excessive soot.

I’m deciding between Mobil 1 Full Synthetic 0w40 and Mobil 1 High Mileage 10w30.

Which would you choose and why?

Cold starting is a non issue, I live in N Florida.

Maxlife 5w30.

Didnt you already use Mobil 1 High Mileage 10w30?
You would say real good things about it in the past
I thought the consensus was 0w40 was a bit more prone to sheering out of grade
At 150k+ miles the High Mileage seems like a good choice

Yea any good 10w30 high mileage oil should work. I try that first in cars that use a fair amount of oil and then go to 15w40 next if it uses a lot.

Had an 08 Escape with the 3.0L V6 for a while, at over 200K it used about a quart per 5K OCI and I was using various 5w30 synthetics. I tried 5w-20 and it consumed about a quart every 1K miles which is why I switched to 5w30.

Mobil 1 10W30 HM

1) HM
2) Lower viscosity spread, lower NOACK

 

[toneydoc]

try Valvoline Maxlife 20w50 and see if that helps

 

[Dyusik]

Toss up, just get the cheaper one.

I'd start out with an HDEO like Delvac or Delo ... 15w40 ought to be better at residual film (cool start) and better at op temp. See how it goes ... If better you are done. If not, you can move to say Napa Synthetic 15W-50 that is on sale right now

 

[1JZ_E46]

Mobil 1 High Mileage 10w30 would work better in my opinion. It’s got a very low NOACK too at 7.5%

 

[raytseng]

try a non-m1 product. Why stick with M1 when you're not happy with the results.

 

[SubieRubyRoo]

Shorten up your OCI and try a different brand oil. Changing chemistries a couple OCI in a row can help clean things up and free ring lands. Sounds like a perfect chance to use some Pennzoil Conventional and a can of Kreen for a 1500mi OCI, then try Maxlife or Pennzoil Platinum High Mileage for a regular OCI.

 

[fordman65]

Maybe a 5w30 or 10w30.
I owned a 01 Mercury Sable with the 3.0.
Owners manual stated 5w30, but Ford TSB came out recommending 5W-20.
I ran 10w30 until I switched to semi-synthic and then ran 5w30. I ran 200k on that motor. Still running after I sold the car.

What's the maintenance history? If you've used quality oils and done appropriate maintenance, then I'm not sure that changing viscosity will do much.

Yep, I needed to go way up to apropiately reduce oil consumption in a Ford Vulcan 3.0 V6. Then I did a hyperflush and problem solved ...

What’s a hyperflush?

+ 1

This should work..

 

[Snagglefoot]

Can you elaborate on the Hyperflush?

A lower viscosity spread doesn't always mean a lower NOACK. Look at the NOACK numbers of all the oils compared in the link below. Lots of instances where oils with large spreads have lower NOACK than some oils with small spreads. When shopping for a low NOACK oil, the actual spec on each specific oil is the best way to compare.
