Recently sent another oil analysis Castrol Magnatec GTX which is still available in Canada, and maybe not in USA. Overall I think it looks good. 3.1% fuel dilution, & some changes to viscosity, probably due to longer idle times in winter. I think this is the 13th sample of engine oil analysis...

2018 Chev Silverado. Truck just recently had a lifter job completed at the Chev Dealership. I was worried I might see higher levels of contaminants. I posted the analysis earlier but they used a diesel motor oil as the reference oil This analysis indicates some fuel dilution, which might not...

It appears the dealer doesn't use the ac delco oil. Any guess what they would use. Engine just had lifters replaced. Wear metals and contaminants look good, but viscosity is out of range. This doesn't look like fuel dilution was flagged. Not sure why it was not in the report.

My son just recently had to do a lifter replacement on a 2018 Chevy Silverado with the 6.2L L 86 engine, with about 91,000 miles/ 146,000 km. We didn't change the oil, & I thought we should be able to pull a sample from the dipstick tube using a 38 U series Vampire vacuum pump and the 1/4 inch...

Is it safe to use Seafoam in all fuels & all models of vehicle. What is the active makeup of these products, and is one better suited than others? I have recently noticed a engine shudder on my F150 3.5 ecoboost, & first going to try cleaning the 3 Mass airflow sensors with CRC product. I am...

My son (23) owns a 2018 Chevy with the 6.2 Gasoline engine. At 144,000 kilometers, or about 90,000 miles it started acting up on his way to work one morning. Initial testing was showing 1 engine code, misfire in cylinder 1 due to bad air fuel mix. Apparently the engine is supposed to use...

Just rolled over 200000 kilometers recently and submitted both transmission & motor oil. A bit of fuel dilution again in this report, but nothing that seems to be concerning. I haven't sent a recent Virgin oil in. Noticing phosphorous & zinc are trending higher than previous samples. Not sure...

Sent another Automatic transmission fluid sample in for my 2018 F150 10R80 transmission. Wear metals are still lower than the first sample I originally sampled They have flagged aluminum at Upper Reportable, 29 PPM. Not sure if anything to really worry about. Not much heavy pulling, mostly...

I have an older Satah S470 Buck tractor. I am replacing the front diff oil/ front wheel assist. The manual recommends a SAE 80 or SAE 90 oil. Would there be any issue using a multigrade SAE 80W-90?

I am almost 52, and have been monitoring my Prostate health with the PSA blood test for about 7 years. My father has also had an enlarged prostate for almost 30 years, & it is hereditary. They have never done anything to treat it, & he will be 82 this fall. I understand there is a urine test...

I recently purchased a Cub Cadet Z-Force SX Zero turn mower. It has the Kawasaki FR730V Engine. They are an air cooled engine, with a 2.2 liter oil capacity, & no oil cooler. I think I am looking for an engine oil with a good HTHS quality. Has anyone used the Valvoline SynPower Motor Oil...

A friend recently had the engine fail in a 2017 Terrain with the 2.4 Ecotec engine. She purchased it new from the dealer and oil changes were being done regularly at the dealer 3800 to 4000 or 5000 kilometer intervals. because it is 7 years old it is out of warranty period with only 82000...

Truck had 175564 km or about 109,000 miles when I sent this recent sample. A longer duration on the OCI than previous sample. Replaced air filter shortly after previous sample at around 150,000 km I think. Boron Depletion is a trending concern. Not sure if AGAT reports it earlier than other...

Has anyone purchased a radon detector to assess, & monitor radon levels in their homes? I live in Saskatchewan, Canada, in an older bungalow built in 1964. The basement floor does have some cracking, & there was no vapor barrier laid below the slab. I also required to install 2 sump pits to...

Are there any simple animated video's available that I can share with a friend that constantly runs engine 1 to 1.5 liters below mid safe range? I am renting a room to a young female 25 year old, & just repaired her rear brakes. I decided to check her oil, & it was right off the dipstick. She...

just changed oil recently & sent a new analysis away. Truck has 149444 kilometers, or about 93000 miles on the engine & a little shorter OCI than the last one. Looks like a pretty good report, but seeing silicon on these last 2 samples have been above the average. Have noticed some oil seeping...

My town has a R.O water system. Would R.O. Water be suitable to flush coolant from vehicle? There is still chlorine added, & probably fluoride. I have a TDS monitor to measure the TDS in water. Prior to the town instaling this R.O. System I had an undercounter R.O. system as well. I could...

What are the requirements for the 2015 KIA Forte, non turbo engine? The owners manual is pretty vague. States 4.0 L of Class API Service SM/ ILSAC GF-4 or above. What exactly is the Total Quartz? A friend has this car, & is low on oil, as in off the dipstick low. Just checking if it is safe...

Recently done a pan drop, & filter change. Sent a sample for analysis before, & after refilling with new oil. I would estimate I got about an 80% oil change Not much of an increase in Iron, & Copper from the previous analysis, & oil viscosity still within range. Slight increase in Aluminum...

I just purchased a Filter Queen Defender home air purifier. Seemed like a great deal for $100. To purchase replacement filters looks like starting at $150 for the internal filter - $250 for the filter & charcoal filter wrap. Does anyone use a Defender air purifier? Thought someone might have...
