hey what types of oil do yall run in your cl? would royal purple be a good oil to put in or should i keep putting penzoil in? i have 127,000 miles on my cl.

 

RP is good stuff, I use Mobile 1 Delvac, the stuff for diesels and trucks, they use it in mercedes and shit

 

it depends if you want to spend the extra coin or not.

 

i started a thread about ths topic awhile ago...u could search for it and maybe come up with some helpful input...but amsoil FTW

 

i was thinking a high mileage valvline.

 

mobil 1 full synthetic

 

Thats what I use in all of my cars also

 

i was using LubroMoly 5-W40. but am currently consuming Castrol Syntec 5-W40.

 

 

mobile 1 full synthetic, you can buy them in 5 gal jugs for 24.50

 

oil filters?

 

i use fram, they are very easy to take out with the non skid padding,

 

Someone i know works in the "car oil" field. He only swears by Amsoil. I'v never tried it myself, but there has been several researches made by his company, it compared amsoil with royal purple. I thought royal was good, but it failed several tests, which the amsoil passed with flying colors.

If your going with a really expansive oil, buy the Amsoil. If you want regular synthetic, go with Mobile 1. Dont even think about getting RP!

 

In my mechanics class, my teacher told us to stay away from those "cheap, large retailer's filters" such as fram, quacker state and so on. He said the best filters for the car is the dealers, and they're not that much more expansive, as well as coming with a new drain bolt washer. I'v also heard good things about AC-Delco oil filters.

But in the end, a filter is a filter, if your going to change your oil often, and keep the engine clean: Changing oil before 5000KM, any filter should be fine. I myself use the AC-Delco filters because they are cheaper than OEM but much better than Fram.

 

oem filter all the way! i get em for like 9-10bucks.

 

thats something new, never had a problem with fram products before. although other products i used when doing my oil change, it was a bitch to get filter out. especially the 2.x since its in the back of the axle to reach it. i guess to preference for which one to use. i think the 3.0 are alot easier to change though.
