I'm the second owner of this car (1978 300CD). It has somewhere around 80k on the second engine block, replaced sometime in the late 90's by the original owner. When I purchased the vehicle, it had not been driven regularly for a few years and had algae growth in the fuel. Several treatments of...

I think this is on topic. Perhaps some midwesterners can give this NC guy some advice. I bought a 1978 MB 300CD a few months ago. Upon getting the car home (a mildly eventful 800 mile drive), discovered quite a bit of rust on the floors and rockers that needed work. After removing the carpet...

I changed antifreeze on a family member's vehicle yesterday, and I picked up a couple bottles of Peak conventional antifreeze. When I got to the point of adding the correct amount to ensure 50/50 mix, I noticed that the sides of the bottles didn't have any marked graduations. There are ribs...

Things are not looking good with the JSW. Iron per mile has gone up significantly and now tin is appearing as more than a trace. Potassium has dropped and sodium is minimal, so I'm not thinking coolant. Silicon is low, so shouldn't be air filtration. My wife's commute has changed from 32 miles a...

I've been delinquent in sharing my UOA data... FYI dealer pressure tested the cooling system twice, once overnight and had no leak-down. Coolant "disappearing" has slowed, and I only added 8oz or so over the last year. High potassium is normal for these vehicles. I plan on continuing 10k OCI...

First sample. Oil is changed annually with a NAPA gold filter. Mileage is low, but this Jeep sees a lot of beach driving. Very pleased with results. I've chosen this oil specifically for it's A3/B3 ACEA rating. Miles on oil 3,025 Miles on vehicle 125,636 Code: ALUMINUM 3 CHROMIUM...

I've already posted this as tdiclub.com and gotten some good feedback, but thought both I and the board could benefit from it being posted here as-well. This was the second sample from the wife's '09 Jetta wagon, and it's third fill of oil (second fill was not tested). Oil is the 507 rated...

Ok, I've searched but still would like an opinion. 1999 Jeep Cherokee 4.0L. Iron block and head, probably aluminum radiator, aluminum freeze plugs. It's been 3 years since I flushed and refilled the cooling system, and at the time I used Prestone AM-AM extended life which still has a green...

I took this oil sample primarily to determine if coolant was present in the oil. The coolant has ever so slowly dropped steadily since new. Dealer pressure tested the cooling system this week and found no leaks. Blackstone had a "?" in antifreeze column due to high potassium. However, on...

The wife and I took our 1 month old '09 Jetta Sportwagen TDI down to the Florida Gulf Coast to visit some family last week. Got back last night and washed the car today. One of the larger bug splatters on the upper hood was tough to get off... Well, after gently scrubbing with the wash mitt I...

2005 Toyota Tacoma, 2.7L 2TR-FE The latest Havoline DS sample is on the left, the earlier sample was Pennzoil YB (SM) on the right. I will say that the Havoline sample had a much tougher life. My commute is now 16mi/day stop and go versus the 50mi/day at low highway speeds I drove on the last...

2005 Toyota Tacoma 4x4 4cyl. Owner's manual specs SAE 90 for the rear differential. This fill was in the rear end for nearly 30k. I picked Royal Purple 75W-90 specifically for its "near" SAE 90 upper viscosity. The RP website used to have it listed around 21cSt, but now has it around 19cSt. The...

Pennzoil 10W-30 YB was on sale last time the '94 Camry needed an oil change, so for the first time since I inherited the vehicle I poured in something other than Havoline. Let me also say, I've run Havoline on all three of our vehicles continuously, except for one or two YB's that snuck in the...

Vehicle is a 1999 Jeep Cherokee 4x4 with the 4.0L I6. It has a lot of driveline modifications and is lifted 5". I don't usually drive it during the week, but on the weekends I'll either take it around town or drive out on the beach in search of surf or fish. I know that beach driving more than...

I guess my choices are Thompson's Water seal or similar concrete product OR garage floor paint. I need it to resist auto chemicals and water. I've already got a lot of damage from a leaky back door, and some spilled brake fluid. The brake fluid pitted and cracked the concrete amazingly fast...

I was actually going to run this for an OCI in the Cherokee, but it disappeared from the local superstore shelf before I had a chance. Grocery store still has it at a reeediculous price. Anyone have any luck finding Havoline HM at a good price? The only reason I'm even considering it is the...

I've noticed that my beloved Toyota oil filters (Denso made in Thailand)appear to scratch my oil filter mount, when installed properly according to directions. I noticed this on my 2TR-FE 4cyl Tacoma last oil change, and paid more attention to it this time. Installation instructions are just...

These pictures were not taken by me, but they're so impressive that I had to post a link. Hurricane Noel was just a few hundred miles offshore at the time. http://surfkdh.com/2007/nov3rd/photos.html

My grease gun had grease leaking everywhere the other day when I was cleaning out the shed. I have a tube of Castrol synthetic #2 lithium soap (light blue color) in there. Now, it was very hot that day, but should grease melt and run at 100F? I don't remember experiencing this before with other...

cST@40C=144.5 cST@100C=21.0 According to revised SAE J306, Royal Purple Max-Gear 75W-90 should be a 75W-110. Any reason why it is not marketed as such?
