You know they've been saying that for years and I understand the reasoning behind the 3K they recommend, but why do I need to change my oil after 3 months if I've only driven 1000 miles?UDTBadkarma said:should change the oil every 3k miles or every 3 months. Which ever comes 1st. Never let oil sit to long.
And that's a valid speculation... but all it would take is a good 30 minute drive to evaporate any condensation build up, no? I mean all cars will collect condensation overnight after they've been parked for the day. That's why they say short drives or trips are not good for a car because it doesn't allow the engine to fully warm up and burn off or evaporate the condensation that collects. Reason I ask is that I received my oil analysis from Blackstone a few weeks ago. My car ran the same oil for 3545 miles over a period of 15 months. So if you do the math you'll see that my car just sits in the garage a lot. The report came back stating the oil was in good condition still (Mobil 1 10W30 full syn) and had no moisture.loosescrew79 said:if only drive 1000 miles in 3 months that means that the car is not drivin that much, which allows condensation to build up in the vacant area of the pan. therefore that little bit of water COULD begin to contaminate the oil. thats why it is just a recomendation
15 months, but I only put 3545 miles on the car during that time...laser2kgt said:im curious, whats the longest any of you have gone with the mobil 1 synthetic w/o a change? i ask because i just got my oil changed a few weeks ago and i got the 15,000 mile mobil 1 full synthetic. i dont plan on changing til next year.
I bet the oil companies love you! Those are standards from like 60 years ago. There have been many advancements in motor oil since then so there really is no need to change it that soon. I'm more concerned about the filter then the oil. My mechanic suggests 5,000 miles or 5 months on normally operated cars. The dealership will never tell you this and neither will any oil company.UDTBadkarma said:should change the oil every 3k miles or every 3 months. Which ever comes 1st. Never let oil sit to long.
