KrisZ, Although it's true that we don't have specific numbers as to what his coolant temperature was in the video when the temperature gauge was at its highest reading, or when it was at its lowest reading near the end of the video, I am confident there was a substantial drop in the coolant...

CB900F2, I slept on your problem and I want to add the following information: If Hyundai did their homework when they engineered & sized the heater core, taking into account the following factors: 1. heater blower motor output (cfm) and resultant BTU loss across the core 2. size of the...

CB900F2, What's happening here is when you have the heater on the coolant circulates through the heater core which is really just a small radiator. When you put the fan on high, the heat transfer across the core is just too much for that engine, in those environmental conditions. Remember...

2010_FX4, I'm with you. It is curious as to why the TAN with EP is so high, with the mileage only about 15% greater than the AFE OCI. And I agree that an 8.9 TAN is higher than I would feel comfortable with. As you are planning to do, I would drop down to a 15K OCI, and retest. If it's still...

toyota62, All SN/GF-5 Mobil 1 oils, to include HM (with the exception of 0W-40) use a calcium/magnesium combination of ~1050/650ppm, as a detergent/dispersant package. Interestingly, Castrol Edge/Syntec does as well, but in the opposite amounts, ~650ppm Ca/1050ppm magnesium. I'm sure one of...

Hokiefyd, +1000 One of the most articulate, well thought-out replies I have seen here in quite some time. Reading it brought back memories of the good old days of BITOG. Take care, Gary

tommygun, His warranty is about to expire (5 years/100000 miles) so Valvoline Maxlife Dex/Merc ATF would be my choice. Out here, Auto-Zone beats Walmart's everyday price, typically $15.99/gallon. Gary

thooks, Seeing that you agree & believe it's really M1, I would keep using M1. We don't see as many M1 5W-20 UOAs with newer vehicles specifying 0W-20, and owners using the M1 0W-20AFE, but the SN version of M1 5W-20 is an incredibly robust, durable oil that gives fantastic results. Keep it in...

thooks, You have every reason to be proud. This is a fantastic UOA. Low Fe, fantastic TBN (3.9) & stable hot viscosity (~8.6cst) after 13K miles. However, are you absolutely positive this fill was PP 5W-20 and not M1 5W-20? The reason I ask is these results show the classic SN formulation for...

ueberooo, I'm guessing, given the variable valve technology that exists, and all manufacturers use, that it would be easy to adjust or delay the intake valve closing and "convert" an engine from Otto cycle to Atkins cycle. Now I would question whether all manufacturers are already doing it to...

2010_FX4, You're very welcome. Between astro14, bubbatime & me, we have your ballistic concerns covered. Now, do your part and keep your F150 UOAs coming. Seriously, realizing your decision concerning using .357 is less critical than mine, grab a .357 barrel and have at it. It should perform...

2010_FX4, I carried the Glock 31 on duty from 05/02 - 08/09. I shot 60k rounds, that's no typo, 60k rounds, through it before I sheared the lug off of the factory barrel. The gun had previously broke the left rear slide rail off, so it made two trips to GLOCK during its life. When I got it...

gonefishing, Good catch!! I guess there would have to be some improvement in the base stock (oxidative stability, etc.) for the EP oil, given its 15000 mile claim. It sure does have similar specs to the AFE, which makes sense as the AFE is a quality product as well. I've got the 0W-20 EP in...

Guys, A few years ago I was a big Pennzoil user, and I still love their Pennzoil conventional, if I had a car that could use it, that is. But their marketing, and more importantly, their distributing network sucks. So, for my synthetic needs it's QSUD or M1. And notice that, unless it's some...

Gene, I hear you and totally agree with you. Another occasional poster here, Salv, is a big believer in Mobil Special. He works for a Hyundai dealer in upstate NY and prefers the Special over the Super that switched to the Na-Ca detergent-dispersant combo. With conventional oil formulations...
