Ok, my apologies for questioning the analogy, the initial question was answered, I was curious if the NG oil could have some negatives if mixed with standard oil, I havent used or heard much about it before.

Water isnt anything like oil... but thanks for the irrelevant analogy.

Thanks for the replies, was mainly concerned about it being made from NG to mix with another type. I have a mix of older SN oils Im using up and dont have anything to use the 3 qts of Pennzoil by itself so will mix with 2 or 3 qts of another SN in a car that uses 10/30, will probably be...

Anyone see any problems with mixing a few quarts of 10/30 SN Pennzoil synthetic made from natural gas with a couple qts of petroleum based synthetic or blends? I have a few quarts of the Pennzoil but not enough for a full change so thinking of adding a few qts of another brand normal oil. I...

Being they are so old I shake them occasionally to avoid additives settling. Think I read that somewhere. :unsure: I do use oldest first, been going off a supply Ive had since around 2005-06, oreillys had a rebate sale that whatever you bought on their list got refunded to you 100%, most items...

I have a lot of older oils that Im just now getting around to using, most are SM but some are SL. They are stored in a insulated & sometimes heated garage so never freezing, I shake them every year or so. Just curious how old is considered too old to use, would be for a mid 2000s toyota or...

thanks! i ended up getting the Mobil 1 for the valvooline sale price.

again, just for general comparison of the 2... you know, like how the VOA section here has hundreds of voa's posted for members to be capable of divining which oil is better?? :unsure:

thanks for the input, i know its mostly opinion based & both are great products that will work fine. i was more curious if anyone knew for example if Mobil 1 has more anti wear additives vs the valvoline. Mobil 1 is usually $14/qt at this store & valvoline is $10, on sale for 7.99. i will...

uh, a VOA would show what additives each one has, just for a general comparison, you know, like the "VOA" subsection on here does? most members here dont just flip a coin...

tried searching for current voa's on these 2 but didnt find much. which brand is the better one? im a valvoline user & found it on sale but they are out of stock, the store offered the mobil 1 at the same sale price. mobil 1 is quite a bit more expensive & i assume its the "better" brand... just...

i tried doing a search for some recent samples of citgo 5w30 superguard synthetic but seem to only find older info from 5-8 years ago. does anyone have or know of any recent used oil analysis or VOA's of this oil? thanks
