First Oil Change

[Grip72]

i get a free oil change from my dealer...how many kms should i get the beast changed at?

[cerbomark]

I would do the first one at 3000 miles (whatever that is in km)... You should have seen all the metalic stuff that came out the first time.

Metal What? Ouch !

 

I got 1,000 miles and after reading above, I am going in for an oil change tomorrow !

Everyone will have their own opinion on this but I change the factory oil and filter at 500 miles, run for another 1500 miles, I leave the AMSOIL EaO oil filter on that I put on at 500 and just change the oil. Then I run that for another 3000 miles which is a total of 5000 on the vehicle. Then I change the oil and filter and start my normal oil change interval. Over kill, yes but I feel better about it. I just use regular oil, ie Pennzoil, Castrol..... up to the 5000 mile mark and then switch over to synthetic. Can you switch earlier, yes but I choose not to. To each his own.

My dealer's service dept. told me to follow the OLM for the first change, but I changed mine at 3,000 miles. I expectted glittering oil and metallic particles in the oil filter, but the oil looked normal and upon cutting open the filter to see the filtering media, there were maybe 4 or 5 tny metal shavings total, nothing else. I would recommend 3,000 miles for the first change.

Had the oil changed yesterday for the first time at the GMC dealership when they fixed my Onstar System. 1000 miles. I'll do the next one at 4,000 then I will start running Mobil-1 Synthetic and changing it every 6000 with a new AC/Delco filter.

First change was at 2500 to Mobil 1. There were quite a few metal shavings on the plug and in the oil. At 5500 I'll change it to Royal Purple.

I had my free oil change at 700mi. Tech said there were metal particulates (shavings then). After that, I just changed it this past Sunday at 4000mi, and switched to Mobil1. From there I'll let it run till the OLM goes to 0%, which hopefully will get me to about Mid March.

Your gonna get alot of different responses on this one, my 2 cents, change at any time before 3,000 miles. I don't think doing it any sooner than that is saving you anything but if that's your preference go for it. My first change is at 3k with Royal Purple and will be done at that interval until the truck is owned by someone else or in the scrap heap.

Did mine at 2500km.

Had my first (free at selling dealer) today at 1,120 miles. Got a free truck wash too.

I hear that the metal shaving s are normal. I don t like to hear that , wonder what that s all about. Never seen as much as on this truck.

[redvett]

I have 241000 mi on one of my service trucks 2000 and have always used the OLM to change & still uses less than a quart in 4000 mi. The other 3 trucks are doing fine too.

[a_guerrajr]

I did mine at 1100, get the crappy stock oil out and get some real oil in their.

[CalixEros]

I did my first change at 2500 to Mobil1, then again with M1 per the OLM. At the next OLM interval, I will get a UOA to see how it's doing. I'll probably switch from M1 to Pennzoil Platinum since the oil's just as good and a couple bucks cheaper. Another UOA on the PP to see which one my truck likes better...

 

Don't know about metal particulates since my first oil change was free at the dealer...
