Mobil 1 full synthetic 5w20 or 5w30 is best in my opinion, and I’ve always just used a fram ultra from Walmart never had any problems and my K20 seemed to enjoy it
My tacoma has 352000 miles have always put mobile 1 in it
I personally have run Mobil1 0w-30 in my GSR for the past 250,000+ miles, since back in the mid-2000's.
Of course, after I bought it I dropped the oil and ran what I like to run in my cars/trucks which a Mobil Delvac product 5w-30. It’s a synthetic but it’s more used for the heavy duty market. I checked the oil some 4000 miles later and it had a reddish look to it just like yours. After the next oil change I never saw it again.
Yooo this happened to me, have you used a high mileage type of oil? Apparently when they start to burn up they can change to a reddish hue, I went back to normal Mobil 1 and it’s back to gold
I’m team mobil 1, 160k and going strong.
Mobil 1 5w30 and oem Subaru filter. I change mine pretty religiously at 3750 miles. I know it might be overkill but I’d rather be safe than sorry and if my engine blows up I will for sure know it wasn’t my fault for neglecting maintenance.
Extractor all the way. As for The amount left behind, it is inconsequential if you are maintaining a short oil change interval. I've seen a couple YouTube videos showing maybe 3 or 4 oz left behind.
Installed new oil and filter, plus BG oil flush, ran at idle for 30 minutes (warm-up, plus 15 minutes). Changed oil and filter again, using Mobil 5W40 Euro oil.
At my 18,000 mile service, barely dropped off full. V.W.they told me at the service has now went with Mobil 1.3,000 miles later down now a 1/2 quart.
