mogandave Posted May 13, 2018 Share Posted May 13, 2018 There is a service check at 5K, but it does not include changing the oil. Chevrolet wanted me to wait until 15K to do the first oil change. Mine only has 12K, but I made them change it already because I think that is way too long to wait for the first oil change. No oil consumption problems have been noticed. I only checked it once before the first change. Seemed fine.I always make them change the oil and filter anytime I get service. When the service interval wad 5k, they wanted to change the filter every other oil change...Oil & filters not really something I need to save money on...

mogandave Posted May 13, 2018 Share Posted May 13, 2018 That is a Weber Genesis gas grille in the back. I had a nice grill for a while, the weather wore me down. Too hot to cook outside... Link to comment Share on other sites More sharing options...

I don’t think I’ve had to add oil between changes in any vehicle since the ‘80s... yeah but they use much looser piston rings now to aid fuel consumption and the result is more oil can be used in this process.

mogandave Posted May 13, 2018 Share Posted May 13, 2018 Machine tolerances and oil quality are so much better now, that oil consumption should be negligent. Chevy specs 15,000km between changes, and the idea that one would be expected to top up the oil between changes is ridiculous. Link to comment Share on other sites More sharing options...

No, not the rings...Depends on the piston material and bore piston clearances they could be bigger or smaller depending on expansion of the piston material used.....

Chevy specs 15,000km between changes, and the idea that one would be expected to top up the oil between changes is ridiculous. GM says normal consumption "can be in the range of one quart within 2,000 miles on a properly driven and maintained vehicle." A quart is about 1 litre every 3200km, which would mean in effect you "could" totally replace the oil between services having none of the original oil left. I dont agree with this amount of oil used being "normal" which is why Im asking owners in Thailand ( as ive only heard the 2.8 in Australia being affected and some 3.6 lit ones in the U.S) source https://www.cars.com/articles/how-much-oil-consumption-is-normal-1420682864535/ Edited May 13, 2018 by kannot Link to comment Share on other sites More sharing options...

The ring manufacturer states the gap for there ring. My fun ride ring gap was (I think) 18 thou in the bore, I spent a lot of time sorting that. Piston to bore clearance is different, a forged piston has a bigger clearance than cast because different heat expansion. If they are saying rings have a bigger joint gap I can accept that..

akirasan Posted May 14, 2018 Share Posted May 14, 2018 My 2006 3L Colorado doesn't seem to use any oil or need topping up in between changes. I change the oil and filter every 10,000 km. Link to comment Share on other sites More sharing options...
mogandave Posted May 14, 2018 Share Posted May 14, 2018 This oil consumption thing sounds like BS to me. I few units or a bad production run perhaps, but in general? Ridiculous. To be clear, taking what a customer claims was said to them by a worker at a dealership and presenting it as GM’s official position is incompetent at best....

I don’t like the look of the mitsu. Isuzu is a good bet. Good service everywhere and much cheaper than Toyota. I've owned several Mitsubishi's - Triton, Lancer and multiple Magnas. They have never let me down, good engineering. I can understand good-looking sedans or coupes. I don't understand how what is basically a truck can be described as good-looking. 1 Link to comment Share on other sites More sharing options...
