I just talked to refiners at Sarnia --and the confirm what Val Christian is saying no ADDITIVE oil is no longer sold. So use NON detergent oil. That will leave the diesel rating out ----so let your turbo cool down a bit longer. For the NA Rabbits ? --best bet is Mineralube. single grade. To seat rings give her snus in short spurts ---do NOT let her idle for hours to seat rings ---you risk Glazing the cylinderwalls and rings may NEVER seat. I am (was) a perfectionist so I honed to a fine finish ----BAD idea today. Really make a good deep crosshatcs ----what is the real word ? hash ? hatch ? What the hell for beginners look it up. . If you do an OLD Rabbit it may be time to look at the new type rings that expand at lower pressures. A standard ring does not really push hard on the cylinder walls in relation to cylinder pressure ---that makes them last longer ---but for OLD Rabbits ? sealing may be more important. Hagar. PS : I have had incredible luck with reworking engines of all kinds ---considering I NEVER was a mechanic (Auto). I have even used owersize rings in standard bores.
