Hi All,
I have just bought a LS400 privately a couple of weeks ago. It has 92k miles on the clock and in all looks in great condition. However after topping up the oil a couple of times, then driving 300 miles, the oil level goes from full to half way on the marks on the oil dip stick. The previous owner completed a full oil change about 5th January 2014, using OEM oil filter and the oil 5w30 from Costco own brand (I am not able to ascertain which 5w30 this is i.e. whether is is A1, A3, etc) . There is no blowing of smoke out the exhaust and there are no drops of oil on my drive. The car runs fine and is lovely to drive. On the long runs I have used cruise control which works well,.
Does anyone have any ideas or suggestions as it is a lovely car and I want to avoid getting rid of it or high expense exceeding car value.
Help!
Thank you for any tips and have a great weekend.
Dominic
