Not sure how many miles I’ll put on it but generally we don’t go by any reasonable amount to use as a change indicator. We almost always go with one year changes. With the twin turbo v6 (and a desire to keep it a long time), is there a benefit to going with 6 month changes?
Thinking of gong 6 month oci on new 2.7l Bronco
- Thread starter Texchappy
- Start date
If it’s under warranty follow the manufacturer stated oci’s
Extended protection products such as M1 EP, VL EP, and Castrol EP are a good way to go in situations like these.
For reference, our navigator (main vehicle for several years) 54k in 11 years from new.
Maverick in just over two years, 4200 miles.
So I’m guessing between 400 and 1000 miles.
1 year oci if warranty allows
While there is no harm with frequent OCI's for most people, there is no benefit if few miles are driven. A one year OCI is still more frequent than necessary and 2 years would be fine for a quality synthetic (let's say 4000 miles over 2 years). As long as your oil warms up sufficiently, there is no real risk. I believe the 2.7L has a rubber oil pump belt (the new version is very tough). The belt will crack over the years if the engine is severely overheated, we know this. Possibly will crack if excess fuel is allowed to remain in the oil.
6 month oci sounds good w the amount of miles your are driving
is it short tripped? what location?/climate
Often short tripped but I try to throw in a longer when I can. Lubbock, Tex -- South Plains — so dry, coldish in winter and hot in the summer. We’re also at ~3,300 feet in elevation.
IMO no reason not to.
I have a tiny notebook I keep in the glovebox as a maintenance log.
tires, oil changes, air filter, cabin air filter, mileage on winter tires & regular tires, rotations etc.
edit: I missed that you would be at 2000 miles a year.. as long as there is no excessive idling or short tripping.
1 year oci should be sufficient but more often does no harm.

6 months is the maximum I would do with any engine with wet belts. The 2.7 (and 3.0 and 5.0 and 1.0 and 1.5) EcoBoosts all have wet oil pump belts now, and they degrade not from the oil but from fuel in the oil.
Get that diluted oil out of there every six months and the belt will last. Leave it in there and it will degrade pretty quickly. I’ve seen it first hand.
My Fiesta ST, 1.5 EcoBoost, has a wet oil pump belts and does very low mileage as I plan to keep the car forever. Six months maximum OCIs for me to save that belt.

I’d just do annual changes.
Seems reasonable. I do 5000 mile changes since I drive 10-15k per year but if I didn't I'd probably do 6 month changes as well.
The engines are moderate fuel diluters by most accounts (2-5%) despit dual DI and MPI. Low annual mileage often equates to short trips, which have a tendency to increase fuel diltution.
There could be some benefit to swapping the oil out, especially at the beginning of the cold season. The 2.7L along with many ford engines uses a wet belt oil pump, and there are anecdotes that having that belt sitting in fuel-diluted oil is not good for its longevity. Freshening up the oil and the corresponding reduction in fuel diltuion after an oil change can't hurt; no guarantee it would really help either. I have yet to see data on the rate of change of fuel dilution, although I've seen one 500 mile horizon oil analysis of the factory fill that indicated 2.5% fuel dilution after that mileage and then 1.9% after 5000 miles. All this intended to say: if you can absorb the cost of a 6 month oil change, I see no problem with it, and it might help....
In piston airplanes we are told by the engine manufactuers to change the engine oil every 4 months or 50 hours of engine operation. I know they are completely different engines (can only use a 50% synthetic blend at most, and lead in the fuel), but I wonder why that is.....I'm guessing low deteregent additive packages due too high operating temps (400F cylinder heads), in turn resulting in faster oil acidity.

You could change you oil for the cost of an oil analysis.
I would just change it instead.
I think I get what the OP is saying. I change every six moths or what ever date is convenient. Usually at the start of winter and the start of summer. If you are concerned about that belt, better still.
My 6 month changes result in about 5,000 miles per interval.

But by doing that one single UOA it could help determine the OCI for the future so in the long run that would save money potentially
