I changed trans and rear differential oil today,and put in some good stuff Motul 75w90 full synth. I phoned infiniti about how many liters oil I should get,they said 2.9L for trans and 1.4L for rear differ,so I bought 5L,1L per bottle. I passed the oil and my car to dealer,and waited about 1 hour untill they give me back,but the dealer gave 1 bottle oil back. According to what infiniti said,I should put in 4.3L totally. They also said there is about 250cc left in another bottle. Is it ok for my car?
