Subaru FB25 oil temp sensor is after oil pump and before the oil filter on the front timing chain cover. Highest I've seen was 261 while towing. Winter temps 190-205 summer temps 210-240. 2018 Forester 6mt.

I have used B12 in the gas tank as directed every 3 tanks of fuel and while my exhaust was off the other day I noted just how clean everything was. Exhaust ports in heads had very light carbon, manifold carbon non existent. Catalytic converter free of carbon, a nice light tan color. AFR and o2...

Unknown. Current owners bought it from an elderly couple that pretty much only drove short trips within town though.

A 2013 Subaru Impreza I take care of FB20 engine using a few quarts per oil change. Owner reporting the level holding steady now at the end of VRP interval 3.

I do not have a "before and after", I have "during" pictures on interval #2 of a heavily oil burning subaru. I will hopefully have an after picture in time. This is one of the cars I take care of. What strikes me is how the deposits are cleaned in blotches. There are small sections where heavy...

I've switched most of the subarus I take care of to VRP with good results

I have seen VRP clean the metal intake manifold on oil change #2 of a port injected engine with egr, anywhere there was oil collected. It was bright and shiny clean. I have no doubt over time and many oil miles this manifold would have been completely cleaned

I second this. I did a piston soak to my Grandmas 2007 rav 4 which went from 3 to 4 quarts consumption in 5,000 miles to less than a half quart in 5,000. Using B12 in the gas tank every 3 tanks as directed has given me a very clean exhaust ports, exhaust manifold, oxygen sensors and cat at a...

Theres a local shop here that absolutely ravages subaru lug studs. I take care of many subarus and have had more than 1 vehicle where I had been the only person to touch the drama free lugs for 40- 50,000 miles only to have this 1 shop rotate tires or whatever and cross thread or compromise 20...

I was at a red traffic light in my manual transmission 2018 Subaru Forester. Next to me was a 2020 ish subaru forester with stop start. Just before our light turned green I began to shift to 1st. As the light turned green I began accelerating. The stop start 2020 ish forester had started and...

I've always given them a light coating of fluid film, avoid severely over torquing and no issues..

Zero on my 2018..

Cvt drain and fill, clean throttle body, clean egr valve and piping, clean MAF sensor., replace pcv valve and hose if brittle. Spark plugs due every 60k.

Is it true that Restore and Protect isnt dexos because it would let the cat out of the bag for its makeup? Didnt valvoline say it would pass dexos easily? You're out of warranty, restore and protect isnt going to hurt anything and depending on the consumption cause VRP may help. It will help...

Valvoline said it may help deal with intake valve deposits in GDI vehicles a small amount. From what I've seen in port fuel injected egr and pcv intake manifold deposits were cleaned away to shiny metal, everywhere that there was contact with oil that pools in intake. I would continue to use...

One in a million... a neighbors often short tripped 80,000 mile 2018 2.4L Hyundai Sonata I take care of. Not any measurable amount of Valvoline Restore and Protect consumed in 5,100 miles. No odor of gasoline in the used oil, the color of the 5,100 mile oil is quite golden still, and is exactly...

I think the OPs coolant in oil could be from the plastic pcv union part under the AC compressor. The FB engine channels the coolant to the heads separate of the HG. 85 percent coolant available to heada, 15 percent available to block when coming from radiator. Drive one watching the coolant...

I would like to share that one of the cars I take care of, a 231,000 mile 2005 Subaru Outback non turbo 4 cylinder manual transmission car has had a large reduction in oil consumption in just its first oil change. The owner changes its oil and tops off. Went from 1 quart per 450-600 miles to...

I'd run the valvoline restore and protect and call it a day.

the likelihood of having a spotless engine under warranty needing proof of oil changes is low. For peace of mind you could purchase dexos oil and return it with receipts.
