What do we know about the technical difference between the Supertech synthetic rated for 10,000 miles and the one rated for 20,000 miles? What has Warren done to make the 20k version last longer? Better base oil? Different add pack? The cost difference between the two isn't even that big.

I am beyond excited at just hearing the news that Mike Portnoy will be coming back to Dream Theater! Mangini is technically good but he is kinda like a robot behind the drums. Portnoy is the closest thing to Neil Peart and I can't wait to hear the music they come up with now! I've seen DT live...

I was looking up the technical specs on Quaker State's Euro L 5w30 and noticed that it's viscosity is 13 cst at 100c, making this oil a 5w40. How can they label this a 30 weight oil when it's clearly out of the range of a 30 weight oil? (it needs to be between 9.3 and 12.4 cst at 100c)

Does Safety Kleen still make the Canadian version of Supertech oils? (they did back in 2009, we know this) I ask this because starting tomorrow Walmart in Canada is selling Supertech synthetic for only $17.47 for 5L jugs, and that has to be the lowest priced synthetic available to us up here (it...

I know that there are only a small number of people that use this oil but I now noticed that Canadian Tire sells Mobil 1 ESP 5w30 in 5 quart jugs. This is especially nice because instead of being $16.99 per quart and never going on sale, it now goes on sale whenever the other M1 jugs are on sale...

Here are the latest oil analysis results for the fourth oil change (and this was my 2nd interval with ESP Formula 5w30, previous two were with M1 5w30) on my 2018 Corvette, analysis done by Wearcheck Canada: Mobil 1 ESP Formula 5w30 Napa Gold 100290 filter 7,400 miles on oil Oct 16 to Sept 19...

I'm curious as to why no manufacturers out there have made an oil filter than is even more efficient than what we currently have, let's just say something that's 99% efficient down to 10 or 15 microns instead of the current best which seems to be around 99% at 20 microns. Surely the technology...

I should probably know these numbers off the top of my head but how do these two filters compare in terms of efficiency? I know the Ultra is built better and has a fully synthetic media, but the NAPA Gold does filter out 99% at 20 microns, and correct me if I'm wrong but isn't this the same as...

I just found out today on the Corvette Forum that this oil can be ordered online from Walmart.com (it's not in stores or available for pickup at this time though) The price is pretty good too, $54.99 for 6 quarts, plus $8.99 for shipping (that's a lot less than dealers are charging for it)...

I sent an email to ExxonMobil to find out the Noack value for their new formula of Mobil 1 ESP 5w30 and they responded back that it's 7.9%. The old version, called ESP Formula 5w30 supposedly had a Noack of 5.6% but that was through independent testing so it's unclear whether or not that number...

How many people here use a torque wrench to tighten your drain plug when changing your oil? I ask this because someone on the Corvette Forum asked for the proper torque specs for the drain plug on an LT1 and I thought to myself "who needs a torque wrench for that?" I've always just tightened it...

Back in the days of GC 0w30 it was quite popular here, and even with the reformulation from the green formula to the gold formula it still had quite a few users on here but I'm curious as to how many people still use it these days? Castrol's website is terrible for finding out technical data on...

A few weeks ago when we got that real cold snap my wife told me her BMW had a hard time starting up one morning, even with it being parked inside our garage (so it was probably around 25-30F in there that day) so I mentioned that it's probably time to get a new battery. We bought the car in the...

Is is true that a fuel with 10% ethanol can actually keep engine deposits lower than ethanol free fuel? And if so, could it be beneficial to run E10 fuel in direct injected applications over E0? (I know the fuel never touches the intake valves, but I'm also thinking of the fuel vapors that...

Fram has been promising us this new 22psi bypass PF64 equivalent oil filter for a while now, and it was supposed to be released in the new year so I'm wondering if anyone has seen this filter yet? I'm hoping it'll be in Walmart before the end of the spring (that'll be when I'll need to change...

My wife and I just got back from a 5 day trip to Varadero Cuba and I really was in awe of all of the 1950s American made cars still on the road there! I had heard a little bit about this in the past from a co worker who was born in Varadero, but I had no idea there were so many of them still...

Now that Mobil 1's 5w30 ESP Formula has been reformulated, I'm wondering if there is another oil out there that has similar technical specs to it that I could consider as it's replacement when my stash runs out? (I just bought more yesterday on clearance at Canadian Tire so I have enough for two...

I recently noticed that Canadian Tire was not replenishing their stock of ESP Formula Mobil 1, and now they are putting their remaining stock on clearance (still overpriced at almost $12 per liter though!) So it could just be because M1 has reformulated 5w30 ESP Formula (and it's now just called...

I'm going to Fort Myers this weekend for a 3 day getaway (Sat-Mon) and so I'm very hopeful for warm sunny weather, obviously. But in checking the various sources for weather out there I'm getting different opinions on how the weekend is going to pan out weather wise. I'm just wondering for those...
