We bought (acquired) an 07 Civic Hybrid with 140k miles. I have no prior experience with any Hondas. This car was was niece's for 12 yrs. I don't think it was "well cared-for" -- based on overall condition, and she was always away from home. I know it was quite low on oil once -- when my brother visited. It calls for 0w20. The oil change sticker was from a Napa Auto Care, said 0w20, and change in 138k. The current oil looks clean, and OLM is at 90%. The car won't be driven much until my daughter can drive it, and we perform some "conditioning & repairs". I drove it home 200 mi this weekend, and it tracks nice, and made 42.3 MPG. I believe there's a bad wheel hub/bearing in rear -- as there's a horrible roar coming from the rear. Assuming it uses some oil, what HM would you choose?
