I would start it if possible not?then at-least your not dealing with a dead battery when it comes time to take it out of storage.
yes use Mobil1
5w-20. I recommend mobil1 synthetic oil.
If you used mobil1 fully synthetic oil then yes. My father and my angle had it happened to them. No leaks no smoke not in coolant. Case against mobil1?
Absolutely! I converted to Mobil1 about 5 years ago.
Synthetic oil.....5W30 Mobil1 or valvoline
Castrol R or Mobil1 Fully synthetic
== == 5w-30 full synthetic i prefer to use mobil1
mobil1
Manufacturer suggests Mobil1 100% synthetic. Synthetic oils have a higher operating temperature the engine will not last if a non synthetic or conventional oil is used because of the high heat especially in the air cooled Porsche engines. Many older Porsche owners say to use a synthetic blend so that the conventional portion of the oil is thought to help keep leaks to a minimum. Mobil1 is my first choice. DO NOT use a cheap domestic oil. Your cars manual should tell you the recommended oils.
Go with fully synthetic 5W30 (year-round). My Altima has 225K miles and I never had a problem with the car. During extremely cold winter months, I've used fully synthetic 5W20. I recommend Valvoline or Mobil1.
Harley recommends their own Syn3 brand of 20W50 synthetic oil, but there are plenty of other brands that will work as well or better, like Mobil1.
Engine oil as specified by Mercedes Benz should be: Mobil1 0W40 Even if you went for another brand I will stick with fully synthetic. 0W40 or 5w40.
