Synthetic Oil

[H2bill]

A question from a new H2 owner.... Is there a consensus here on synthetic vs. dyno oil? I was kind of surprised when I read my manual that the H2 didn't come with synthetic motor oil. Are there pros and cons unique to the H2 that I'm unaware of? I run synthetic in both my BMW car and bike. Do folks just switch over when they feel like it, or is there some other Hummer guideline? (With BMW motorcycles, the consensus seems to be to run dyno for a couple thousand miles before a switching to synthetic). Are there any warranty issues with going to synthetic?

I did a search but didn't find this particular question addressed. If the topic has been discussed (ad nauseum) here sorry, please post the link. Thanks.

PhilD,
Again, apologies for being a nOOb here...is there a specific Hummer oil filter that is preferred, or is any after market GM specific filter considered good to go. My only other similar experience is with BMW motorcycles and analysis has shown that it is actually worth using the BMW filters over the aftermarkets.

yeah phil, what about the K&N Performance Gold filters. OK by you? I think you once said you use Mobil 1 filters, not sure if you've tried anything else.

I thought I've read that it's good to wait until about 15k to make sure seals seat properly

I have heard that some sport bikes that have ceramic coated cylinders have issues with Syn oil. Other than that, I have never heard anything except to allow break-in period to occur with dino. There has to be some truth to the rumor that syn oil has less friction because engines run cooler with it. My Harley runs 20 degrees cooler with Syn oil.

I am switching over to Mobil 1 with Mobil 1 extended performance oil filter. Then I will start using the electronics tell me when to change the oil instead of changing it every 3k miles. The decision to switch over was hard for me because I get $20 oil/filter and lube at local Chevy dealer.

Now I will have to change oil/filter & lube myself and will still cost me almost $40 to do it. I am going to justify it because I will go longer between changes and engine will run cooler and may have less wear.

I'm using a K&N 1007 and Mobil 1. Just switched to synthetic last weekend and I"m doing the oil/lube myself now.
