So, I'll make this short. Had Ravenol in my Subaru about 2 years back, and OCI was cut short at about 6k because it leaked enough (ends up on exhaust, smells very much bad) I ran out of Ravenol makeup. I then ran an OCI of VMLFS way longer than I intended (around 10,500 miles and about 8 months) and barely had to add anything, maybe a cup to a pint during the whole thing. Friday, I decided the Ravenol thing was a fluke, either oil or car related and decided to run it again since I had a couple 5Ls on the shelf. Well, by Sunday morning the drip is back, enough that if I let the car idle with the hood up you can see what's burning off the exhaust.
Question is, I thought d1G2 oils had similar seal conditioners to what's likely found in VML. Is the PAO/Group V oil just that more aggressive on seals? Should the drip reappear in less than 100 miles? And I don't need "well fix the leak" because I know that, but I'm not going to drop a couple hundred bucks (maybe a grand?) to pull the engine and replace some seals on a 16 year old vehicle that's just a work car. I'll obviously just go back to the VML after this OCI and use the other jug in my other vehicle.
