Which motor oil will you go with – page 8 – subaru ascent forum gas stoichiometry practice sheet

##########

I know very little about cars/engines but I thought I read someplace that oils like Mobil 1 ESP that are low sulphur(or low ash?) are also useful in preventing carbon build up on valves etc…..Does anyone that is knowledgeable know if that is true or unproven internet speculation?……if true , what would be a good oil choice? Also, is a low NOACK value or a high NOACK value good? Is there a way to determine that value from the oils specs if it is not stated as NOACK value? Like I said, I know little about this stuff but figure I might as well buy the best oil I can since I need to buy oil anyway..

There’s a lot of things at play for intake valve carbon buildup across many manufacturers. VW/Audi/BMW had some major issues with it years ago when they first started using their turbos because of the way they did EGR and it had unburned oil/fuel droplets. This is why so many people suggest a "catch can" but I don’t think it’s necessary in our vehicle. Subaru has the advantage that they’ve seen the issues from other manufacturers and have been able to tweak the engineering. u gas cedar hill mo Toyota has a "foolproof" system with the double-rail fuel injectors which uses port side injectors when it’s idling or at a steady highway speed (with reduced RPM/demand on the engine) and uses the DI for everything else. gas vs diesel prices The biggest downside of the Toyota dual-rail system is that if you ever need to do repair work on the injectors, you have a major cost on your hands because it’s a lot of extra labor – I think I read about 8 hours.

Don’t get too tied up in the NOACK values – you want lower, I believe, which stands for more resistance to volatility. The reason why NOACK is important is because the thinner weight oils that manufacturers are using to improve fuel economy also tend to be more volatile. So, if you have volatile oil that is evaporating, that has to go somewhere. Which means along your exhaust system, adding to wear-and-tear. electricity water analogy animation It’s not the blue smoke like your father’s-father’s junker, but it’s not a good thing nonetheless.

I also, personally, think that the OEM Subaru oil manufactured by Idemitsu is acceptable. I think the biggest thing you can do as an owner is maintain it at regular intervals. Again, I personally am going to run the OCI on the "severe service" interval, because it’s cheap, and usually I only drive around 1000 miles a month. Down the road as we know MORE about the FA24 engine, I may extend it. electricity cost nyc But I don’t want to be the test pilot here.
