Is this coolant ok for an all iron SBC with an aluminum radiator?

Burnt #3 cyl exhaut valves about 30K ago. I replaced the valves (just lapped them) and now it has done it again 30K later. I'm replacing the head with a remanufactored one along with new fuel injectors. The injector for that cylinder is the only thing that I can think that would cause it? Any...

Hey guys, I have a 2000 Honda Accord (4 cylinder) with 395000 miles. I replaced the engine at 290000 with a used serviceable unit. It has done this for awhile and I cannot find the source... It produces a noticeable burning rubber smell when climbing a significant hill at highway speeds. It's...

I recently found this on some Supertech ATF and coolant jugs. Here is a picture of the ATF jugs. Look at the level markings-the jug on the right has markings that indicate a liter being a greater quantity of fluid than a quart! Here is a jug of coolant I purchased the other day. It's...

I am helping a friend get all the servicing on his truck up to date. He is unsure when the last time the trans was serviced (truck has 130K, auto trans). Factory fill is Mercon SP, however most online sources show Mercon LV as the correct fluid to use. The plan is to do 3 drain/fills in close...

Guys, My Silverado seems to be slipping very lightly on occasion during the 2-3 shift. The trans has never been neglected, regular service, etc. Currently has Dexron VI as the fluid which was serviced about 10K miles ago. I am not mad or surprised, the truck has served me well and will continue...

Removed this filter from my Uncle's 2002 S10 (4.3 V6) today. Roughly how old is it? Will give us an idea of how long it had been since it had the oil changed.

This quart of Lucas has been on a nearby retailers shelf for quite awhile. It's a hardware store, for whatever that is worth. Notice the label taped back on!

Long story short, I have a 2000 Honda Accord EX 2.3 beater car. I take good care of it, but I try out various oil additives from time to time. Pretty much tried everything at WalMart, MotorKote, various mixes of oil, 5w-30 to 20w-50, etc. Open to suggestions within reason. I am not going to do...

This goes WAY back to 2002, but I wanted to mention it due to being an oil related 'issue'. The long story short is that I have owned several Toyota Supra's over the years and have worked on a few friend's, etc. Anyway, this was a friend's car that he recently purchased and wanted me to do a...

The long story short is that I got this car (2000 Accord 4cyl) from a friend awhile back, he got rid of it because it started making this noise (nearly instantly) during the short time he owned it. I don't blame him, I would of gotten rid of it also! Anyway, I have driven this car over 13K...

That it is mixed stronger than 50/50 (which should test -34F), anyone else ever seen this? I have some premixed in the garage now, I will test it here in a bit and post the exact number that I get.

This is my 2000 Honda Accord 'beater' car. The compression, and more importantly, leakdown numbers are excellent-leakdown was less than 10% on all cylinders. However, it blows a massive amount of air from the oil fill. If you can't tell what I am doing in the video, it's holding a paper towel...

So...given what happened in my other thread... https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4657581/Crazy_oil_change_(fail)_story_#Post4657581 I just had to see how many quarts of oil a Small Block Chevy (79 305 with 5qt pan) would hold, filled to the brim, coming out of the...

I keep forgetting to post this, just doing it now real quick while I have it on my mind.. I was 99% sure that this was true, but I was able to verify that a guy that was a few years older than me (High School days) tried to change his own oil.. He filled it up. All the way. Till it was coming...

Hey guys, I have learned a ton here over the years without starting to many threads, but I can't seem to find an answer to my question. A friend brought up this subject yesterday and I was not able to add too much to the discussion.. Anyway, why/how is there such a variance in the pour point...

Hey guys, I picked up a bunch of Idemitsu 0W-20 from Advance Auto on clearance. I have always understood that mixing oils of different weights will net the average viscosity of the oils used in the mix. With that said, I recently changed the oil in my truck (2005 Chevy 5.3L) and beater car...

Hey guys, I bought my 2005 Crew Cab Silverado (5.3L gas) in 2010 with about 89K miles. I am pretty sure that the previous owner said that he changed all fluids at some point with AMSOIL. Fast foward to now, it has 197K and I have changed every fluid other than the trans fluid, which is still in...

Guys, I posted about this before and just wanted to follow up. When I was last home in November (I work overseas), I purchased a vehicle that was serviced with OAT coolant at the wrong mixture for cold Upstate NY storage. Given that, and the fact that it was supposed to have HOAT coolant, I did...

Guys, I recently bought a Viper that I have learned from the shop that built it has Dexcool in it. I need to change it as it's not properly mixed for NY winters. My question is, if I completely drain the system (block included), will I be fine just refilling with the proper Dodge HOAT coolant...
