I guess I'm the only one on here that still uses conventional oil - Penzoil 5W30 in the 05 & 10W30 in the 03 - every 3000 miles. I try and find a good oil filter like K&N or Bosch - I won't use the cheap fram filters.

 

I use Mobil 1 5w30 with a Mobil 1 filter.

 

I'm not sure what I'm going to stick with in the long run. Right now I'm currently running with Valvoline High Mileage Synthetic, but I might change that depending on what I find out.

 

I'm still undecided what to run in my Dale Jr car. The current oil change is still good for about 1,500 miles and the sticker on the windshield says Quaker state was used.

I'm currently running Valvoline conventional in all of my other vehicles and is what I'll probably run in this car. I don't like synthetics so I doubt I will try any of them.

Hey Since i owned 05 Monte SS I have only used 5w30 Royal Purple with a wix Filter.. I for sure sue synth Becase Just starting my car in the -30s weather HELPS.. My old car i only used regual 5w30 and old car seem to start harder and didnt idle as smooth.


1 thing i noticed befor i purchased my car thier was no oil pan gasket leak. and since ive owned it its starting to leak and has been gettin worse. I think its the synthetic being soo thin im not sure. but warrenty should cover to replace oil pan gasket

 

I have a 03 monte SS.I want to modify the engine what should I add.I prefer for it run quietly but powerful.Should I change the stock into morso spiral flowor 3a racing muffler?Also will it harm my trans?Thanks for the assistance!

 

With me it was the opposite. I would notice in plenty of my cars if there was a small oil leak here or there, and I would switch out the oil with syntec, maybe add some lucas, the floor would be bone dry. I guess thats why I stick with syntec now.

Im not 100% sure whats leaking But oil pan is coverd.. Antie Frezze is up and powersteering is full. Soo my only guesse is oil evry 5000ks befor i do oil change I notice about .5Quart Missing /burnt/ Leaking.. But i have warrenty for seals and gaskets for 1 more year soo since its starting to leak get it fixed for free Right.. And its leaking Right Where you cant get to the oil pan bolts.. its like a subfram under pan. Right side???


What do you mean the floor would be bone DRY? I was thinking of adding some lucas as i work at a truck shop have lots extra lucas... So its ALL RIGHT to put lucas in synth.
