what mileage should I change it out at, 3k?

Best of luck. Iām 1000 miles into my first full concentration VRP oil change on my 2012 Impreza with the FB20. I had done a 50% VRP/50% RGT 2000 mile interval prior to this and Iām already seeing significantly less oil consumption. I was having to put in .5 quarts every 1K miles but so far sheās holding steady.I havenāt posted here in years but saw this super long thread and wanted to add my read world test into the mix. I donāt have any pictures but I am currently starting an OCI of the Valvoline Restore & Protect in my 2011 Forester. This is one of the early oil burning FB25 engines. Low compression in at least one cylinder and running this oil to see if it might help clean the rings and fix the compression issue / oil burning. Burning about a quart of every 700 to 800 miles currently. I am not expecting anything major but had nothing to loose except the money for the oil.
If it doesnāt help, I will be replacing the engine soon.
I will update once I get some miles on it. I have 45 miles on the OCI so far.
Iād sell that thing and get a 16 year old something safer. The 2004 and up F150ās are much safer.
leave in til 5K or until the Maintenance Light reminder lights on. Just swap the filter half way and top off if you are concerned. Just my honest opinion and course of action. Check the dipstick often per XXX miles driven.what mileage should I change it out at, 3k?![]()
That gives me some hope as that engine is very similar to mine and from the same era. Although mine is using a lot more oil than yours. Time will tell!Best of luck.

I wasnāt advocating that he should get an 04+ F150, but if heās gotta have an F150, Iād rather put my kid in a less reliable but safer car any day of the week. Im not a Ford guy, but a properly cared for 3V 5.4 is capable of 200k+ miles. I wouldnāt knowingly and purposefully put my kid in a 97-03 F150, would you? Crash performance doesnāt matter until it does, then itās the only thing that matters in that moment. The difference in the two body style trucks of the same make/model is the difference in dying (or having life altering injuries) in a crash and walking away with minor/non life threatening injuries. A teenager is more likely to wreck a vehicle than they are to wear it out, in my opinion.2004 and up F150s are much more unreliable. The 5.4 3v is a garbage engine.
Have you tried heavier oil in the past like 15w40? Gonna replace the engine soon anyway so might be worth a shot to get the burning downI havenāt posted here in years but saw this super long thread and wanted to add my read world test into the mix.

My condolencesā¦.. maybe itās time to upgrade?Thanks a lot! I have an 01 150.
I will recommend short changing your oil filter. On my 50/50 concentration run, my filter started making a tapping sound at startup at about the 200 mile make. I presume the bypass valve was opening. I changed it out for a fresh filter and it stopped the noise.That gives me some hope as that engine is very similar to mine and from the same era. Although mine is using a lot more oil than yours. Time will tell!
I did try a 40 weight oil. It made no difference. I already was using 5w30 over the recommended 0w20 by Subaru.Have you tried heavier oil in the past like 15w40? Gonna replace the engine soon anyway so might be worth a shot to get the burning down
Thanks! I do have a spare filter on hand.I will recommend short changing your oil filter.

Iām at 1K on this OCI which is 100% VRP and the filter has been sounding fine thus far but I have a spare filter in the backseat along with my three claw filter wrench in case I hear that tapping sound again while Iām away from the house.

It doesn't have to be anything missing.The fact that R&P doesn't have Dexos cert. was briefly asked in this thread, with no answer. What would be missing in oil properties without that cert? It seems just about every other consumer grade oil is blessed with that cert, but here not so much.

Just means they don't want to spend the money on achieving the certification and/or they don't want GM to learn any trade-secrets in this oil.The fact that R&P doesn't have Dexos cert. was briefly asked in this thread, with no answer.

Perhaps. Or it can be that one parameter slightly exceeds or underperforms, neither one of which makes it āworseā in any meaningful way. Some dexos requirements are not geared towards quality as such.Just means they don't want to spend the money on achieving the certification and/or they don't want GM to learn any trade-secrets in this oil.
