Just realized I left this thread abandoned, although not really cause it's obvious there's a general consensus when it comes to rarely driven cars. It's not so much that they have special needs, but mostly that around my neck of the woods what you get in every shop is at most a mediocre...

The problem in my case is mostly waste. I try to change oil in all 3 cars at roughly the same time and that means 18 empty 1qt bottles (it's impossible to find gallon jugs for the oils I use) and about 4.5 gallons of "used" oil that I have to go and dispose of properly. From what I understand...

Thanks for your replies, folks! I don't think there's a place where I can send oil for analysis nearby so I too go by looks and smell. The oil I changed in the e39 and the pathy was still translucent after 1.5 years and now after reading all the replies I feel bad I threw it away. Unrelated but...

Hi folks, I have 3 cars that for the past ~2 years have been rarely used ever since we were sent to work from home. In average each sees 2k to 3k miles a year. I do drive them at least 30 min once a month or more (not just a warm up). I recently changed the oil in 2 of the 3 cars after 1.5...

Thank you all, extremely useful info all around! So basically what I suspected is right, W rating is negligible around here, but I should stick to the required oil grade for the engine (as I've been doing since forever). Seeing folks from Down Under and Florida replying here makes it more...

Thanks. I do understand that at a high level but I'm not that familiar with pumpability values and don't know if, say, in the table above the 582 Cst viscosity at 20 C is on the low or high limit for the average engine. I would say that temps around here drop below 20 C (and stay in the high...

Hi folks, First time poster here. I searched all over the internet but it seems I'm the first one to ask this very specific question: It's clear that all other things being equal, a lower "W" rating is preferable (e.g. 0w-40 better than 15w-40). However, almost all information refers to places...
