What oil weight is everyone using?

[cobraken]

Looks to me like everyone is running all kinds of oil types just fine and that I might be a good investment to get the ZDDP additive.

Just switched to 15w50 Mobil 1 -- love it!

lol i just bought 15-50 mobil 1 today. what an expensive oil change. $7.49 a quart!!!

[nando]

15-50 Mobil1 here. Get it in the BIG jug! It's a bit less expensive.

[richardkeith97]

they only sell 10-30 mobil 1 here in the jug. thats the only reason i was using 10-30 in the first place. its like $22 for a jug of 10-30

[sector6]

it's about the same ($22-ish) for 15-50 at my local walmart.

It's most generally not recommended to switch to a diesel oil once the engine has a good amount of time/mileage on it. If you use the diesel oil after running conventional oil for a certain period, the extra detergents will remove the carbon build up causing engine problems. If the internals have recently been cleaned and spec'd, then you are good.

That's just the general concensus.

Bellingham walmart was always THE place to get good oil for cheap...walmarts here are bigger but the oil selection sucks.

For those who don't have a bentley manual. As you can see 10w30 is really best for temperatures under 40, so leave that for the winter. However I used 10w30 for a couple years and it did pretty well but it did leak.

You guys should go check out Mobil 1's web site. If you tell it what kind of car you have an how many miles are on it the website tells you what you should be running. I did this on my cars and it said Mobil 1 (0w-40).

Mobil1 Recommends using their special oil that is pretty pricey just like Bosch recommends using +4 Platinum Spark Plugs! They're just trying to get you to buy their most expensive product.

Anyone ever used LUBROMOLY? I've got a jug that I'm going to use next oil change, I mainly just wanted some German oil but it is probably not worth the money.

Mobil 1 15w50, been using it since i got the car.

it also stopped the small oil leak it had when i picked it up, car runs great with it.

its nice, i stock up filters and buy the oil on sale, tipically my oil changes have been
running ~25$ with this system, i like it alot.

the same has been said for swapping to Synthetic after you have lots of time running conventional. Both are hog wash, if the engine has been well maintained in the 1st place.

The only thing I have seen this happen on was a beat to death 250k mile yota minivan with a old 2.2 in it. that was swapped to syn the thing hemorrhaged from every seal know to man.



Guys stop bitching about how much you oil service cost in supply's. Its cheap compared to a failure, an leaving you stranded some where. My truck is well over a 150 bucks to service, Oil is 44 a Gallon and the crank case takes 2 1/2 gallons, filter is 21, Fuel filter is 45, Air filter is 36ish trans Spin on filter is 42 from the dealer, but I get mine through Allison for 14, grease is cheap so I dont count that. I service everything at 7500 mile intervals unless I have a lot of heavy towing on that service. Could I do it cheaper sure I could, but then I would compromising quality of materials and supplies, and thats something I am not willing to do as my truck has to be 100% reliable and work in even the most severe conditions. Your vehicle is only as good as you take of it, and as good the materials that you use. A chain is only as strong as its weakest link, and the same goes for your maintenance materials.

Dont get me started on the tranny, that was expensive as well, but trans temps even in the dead of summer with a heavy load on still never get over 180* with just a fluid upgrade (100% Syn, Transyd made by castrol for Allison) total swap out. and also get 10-12% better fuel economy when empty.

20w50. Just 2300 miles to go til 300k and it sees almost 7000 every day. I literally can't kill the thing but it does leak a little.
