Truck Oil change intervals

[buickanddeere]

Does this truck have direct injection for fuel delivery? Not familiar with Chevy. If so all manufactures have been plagued with fuel getting past the rings and diluting (washing out) the oil. Oil with fuel in it breaks down very quickly and will cause issues with timing components. If so then change the oil no longer than 5k and less if you have an engine that has some blow by due to ring gap clearance issues. If no direct injection then you don't have to worry.

To answer your question, only a synthetic filter can last as long as synthetic oil. Since you have filters already, just change the filter at 5k and add oil to top it off.

I have a Ford with the ecoboost (TTDI) and it's hard on oil. I use Mobil 1 extended performance and change every 3k miles because of the DI and high pressure fuel pump. It's good oil...

Some Chev 2.4L four cylinders in 2010-2011 had common rail pump seal problems which dumped gasoline into the crankcase. The gasoline was not going past the piston rings.

So I have a new 2014 Silverado 1500 LTZ Crew Cab 4wd with the 5.3 V8. I have been a Mobil 1 user for years. Mobil 1 has this new oil out that is guaranteed for 15k mile oil change intervals. However I like using the AC Delco filters, which I already have 2 setting on the shelf. My question is, and Mobil cant answer, does the AC Delco PF63E filter have the capability to go 15k miles also? Not sure where to find this info. My Oil life monitor system goes off at about 8k miles. I'm just afraid the oil will out live the filter. I can buy the Mobil 1 filter also that is good for 15k miles or I could just keep doing the oil changes at about 8k miles or probably 10k. Thoughts?

I don't like taking chances for nickel dime stuff like this so I change my synthetic engine oil (Mobil 1) every 5000 miles along with the filter. Changing oil without changing the filter is like taking a shower while wearing a raincoat. The pennies saved by changing out the oil less often than I can stretch it is nowhere near what a new engine or engine overhaul would cost. I think they call it penny wise and pound foolish.
I ran the same 5K mile change schedule back when I was running Amsoil which supposedly never needed to be changed, just filtered better and analysed. Maybe it's better to just buy the cheaper grade Mobil 1 and change it out.

I ended up taking back the PF63E AC Delco filters and bought the Mobil 1 filter. It was on sale at Oreilly Auto for $9.99. Changed it yesterday to the M1 0W20 Extended Performance oil and filter. I think I will go by the OLM and see how many miles before that kicks in. This time around the light came on around 7500 miles or so. I don't think I will run the full 15k miles M1 recommends but maybe stretch it to 10k mile intervals. After all, what's the point of spending the money on quality synthetic oil and filter if you are just gonna change it at regular intervals? I'm sure the OLM in the truck isn't based on synthetic oil since the first 4 oil changes were free and they use an AC Delco synthetic blend for those changes. Anyway, enough about oil. Go Royals!

The AC Delco synthetic is Mobil 1 and the blend is also a Mobil product. At least where I worked. Corvettes call for Mobil 1 so I would think. All bulk oil deliveries were I worked came out of a Mobil delivery truck.
