Hi,
A couple of unrelated questions. If this is the wrong sub-forum, apologies.
First. While changing the motor oil in my mother's Outback 3.6R (6 cylinder boxer), she mentioned the dealer used 0W-20 instead of 5W-30 at the first change (around 3k), by accident. It has since been changed out to the correct weight (5W-30). As the break-in period happened with the correct weight, but the subsequent fill was incorrect, is there any chance some damage was done? Engine and drivetrain "seem" fine, car runs like a champ. Poured regular flavor M1 5W-30.
Second. Recently had a 22kW Generac 2 cylinder backup generator installed (999cc engine, air cooled). Runs on propane. The installer mentioned that during extended runs, checking oil level will be critical and to expect "heavy" oil use/burn. Suggestion was to top it up with fresh oil as needed and continue with regular maintenance. The burn rate mentioned was about a 1/2qt every 24hrs!
Is this the norm? Do these engines seriously consume oil at a high rate? Manual calls for 5W-30, with the first change at 25hrs, and every 200hrs thereafter.
Additional question regarding: Is 5W-30 the right weight here, considering the consumption rate? I've been using 15W-50 M1 in my cheap-o portable with good results and minimal oil burn. And my Honda eu7000is generator that uses 10W-30 doesn't burn a drop. What gives, Generac?
Thanks in advance for any help/suggestions!
