Is the RL/Amsoil protecting or providing any benefit over that OCI if the T6 holds up just fine? Like you, I dont plan to replace the motor, and am hoping to eek out 200k moreo on my STI and 100k more on my Leggy, but I'm not sure that can't be done doing what I'm doing. I am open to change, though.
What I'm doing:
97 Subaru Legacy (203kmi): This is my DD and winter driving car. I work 3.6 miles from home. I run errands a few days a week, and sometimes make longer, 50+ mile trips. In the winter I make most of my long distance trips - 1-1/2 hrs down to see the gf every other week + where ever else the wind takes me on a given weekend - in this car, so it does get plenty of highway miles. In the warmer months it's mainly a back-and-forth-to-work car, but will still see a few longer trips. FWIW, this will be my first time running the oil out to 10k on T6.
08 Subaru STI (19kmi): This is my nice-day, summer driving car. It mostly sees the highway, with spirited on-ramp jonts, and weekend days on the back roads. Overally I'd say it sees 80/20 highway. My last OCI was 4600 miles, this one will be 7500, and the next will be based UOA results. The results at 4600 - my first run on T6 - seemed to have a lot of life left.
Neither car burns any oil at all, though the Leggy did burn 1-1/2 qts when I first switched over from GTX HM to T6 over the first 1500 miles. I'm at 5000 miles now on this OCI, and haven't burned a drop since.
In all honesty, I would get some UOA's of these 10k runs you're going to be making and go from there. I am certainly not saying that what you are currently using can't or won't hold up to that length. You may be really happy with the results.
My vehicles, mileage-wise are similar.
S10 has 186k or so and the Solstice has 11k. The SSO in the Pontiac can flat out absorb some miles, although with it being a turbocharged motor, the warranty distance is less outside of sampling the extension of the warranty further.
It sounds like you take care of your vehicles.
How many miles a year would you say you're looking at putting on both, if you had to figure a number?
