Hey, Just changed my oil and oil filter today (10000km). Firstly, i changed over to synthetic oil (caltex brand) and i was wondering if compared to mineral based oil if there was a difference in how much i should be using? At my 5000km oil change, i put in 2.5L of oil and that was about the middle of the two indicaters. Now however, i put in 2.5L of synthetic and i get a really low reading of oil.. Is this normal? Should i be putting more oil in than average beacause its synthetic? How much oil are you guys putting in your engines? ANybody got any good tips for removing the oil filter so its easier next time? Thanks
