Hi team Just when you hoped the synthetic oil thread had died...
Here's the Mobil 1 oil and drain interval recommendation I received from Mobil NZ yesterday. >> Unfortunately, we do not have the Mobil 1 Truck & SUV 5W-40 in NZ or Australia. Our closest would be Mobil 1 5W-50. The information I have about your vehicle is that you need to use an oil that meets Mercedes Benz spec 229.1, which this mobil 1 does. Being an old car, the previous service history would have a bearing as to how good a choice Mobil 1 is. Mobil 1 cleans better than most oils, so as long as the car is sound in condition, Mobil 1 will be fine. Things to look out for are oil consumption. As far as oil drains are concerned, change the first one at 5000, to get rid of any muck Mobil 1 has managed to clean off, then go to 10000 km's. Regards MOBIL LUBELINE << >From what you guys say, Mobil 1 5W-50 would be suitable for very cold conditions. At my end of NZ, however, our temps range from minus 3 to 5 C (rarely) to +30 C (occasionally). A very equable climate. The other oil option you mention (Mobil 15W-50) does not meet MB specs according to the information on Mobil NZ's website ( http://www.mobil.com/New_Zealand-English/Lubes/PDS/ GLXXENPVLMOMobil_1_15W-50.asp) but it meets 229.1 on www.whnet.com/4x4/oil.html. Huh? BTW I mentioned this synthetic oil discussion to my highly and widely respected MB specialist mechanic yesterday. He wasn't enthusiastic about me changing to synthetic oil (why go to that expense? - change the dino oil more frequently and know you've got all the waste products out - how environmentally harmful is burning waste synthetic oil?) The last question is a good one, since NZ burns rather than re-refines its waste oil. Anyone got any info on that?
