I've had a great experience using Blackstone Laboratories for oil analysis testing. I've always received detailed and informative reports, and I'm very happy with the overall results and insights they provide. My only complaint is the turnaround time, as it has been a bit inconsistent. Sometimes I received results in about two weeks, while other times it took closer to a month. Overall though, it's still an excellent service that I'd recommend to anyone wanting to keep a close eye on their engine health. read more

Really impressed by the personalized service for my dinky little account, two diesel boat engines tested every few years. Their last report included a paragraph of discussion and advice, personally addressed to me. Real people answer the phone every time; for one question I was transferred to talk directly with an analyst. Wish I had more business to throw their way, but I recommend you give them yours. read more

Super helpful and knowledgeable staff. Brian Despain in particular is a pleasure to deal with. Exceptional customer service skills and prompt responses from this group. No hold time while calling and I spoke directly to competent employees, not a recording. Highly recommended company with great employees. Thanks for your help! read more

No way, never ever again... Find a real lab, their results are very questionable. I sent in some badly burned oil from a motor that was grossly over heated. They said the oil was wonderful, no worries... I tore apart the engine and found some pretty ugly sludge and a great deal of metal. These guys are not worth the money and they draw a major vacuum on a column of mercury... Shop elsewhere or waste your money to hear bogus "good news" I think testing diesel is their limitation at best, not motor oil from a IC engine. read more

I have used BL for a VERY LONG TIME ( Let's just say that I've known them since they were on S. Lafayette Street) !! For those of you who lease a car every 30 months or so, don't waste your hard earned money. You'll be clueless and think this place is useless. I never do an oil analysis on my leases or a car that I will get rid of in no time. They get beat up and on to the next person to be liable, haha. However, with my keepers like my classic cars which don't get driven much, BL has saved me mucho time and money just on the oil changes and extended oil use. Every one of my classic cars is always ready to be driven, so the motors and transmissions and all of the oils and fluids need to be clean and ready to go at all times, and that's where BL becomes very important to me and my classic babies (besides my fur babies who are also very important to me, that's a whole different review in the future)!! An oil analysis is like doing your blood test for your annual physical. It tells me how my classic babies' motors are running and it tells me whether the content of the oil is still in tact. The best part of the analysis is that it actually can tell me if a $15 a quart bottle of oil is really worth it or maybe that $2 per quart oil is the same as that $10 per qt oil....Many of you may think you're putting that $20 a qt oil in your Lambo or Bently is the way to go, but it may just be the same stuff you can buy for $5 (oops, now the news is out...hahaha). If you have 10+ classic cars like I do at 10 to 15 qts per car that's over $1000 to $3000 of savings a year my friends!! Trust me, I may not be an auto mechanic expert, but with the number of cars I have, BL has already saved me thousands over the years. Thank you Blackstone Lab. Not only my babies are purrrrring so beautifully, but I could now afford to wine and dine at some of the best yelp rated restaurants!! Ha! read more

Blackstone Labratories - BL and my Classics...haha - Automotive Near Me - Fort Wayne, Indiana

See all

Blackstone is the country's premier oil testing lab. They test engine oil, transmission oil, differential oil, for passenger cars, work trucks, light aircraft, etc. I've used Blackstone for several years now, to test engine oil to check for premature wear on my BMW M cars. Their analysis is extensive, inexpensive, and most importantly their customer service is outstanding! read more

Save your money and time and effort for better places. I paid and tried this place and to me they probably just mess around and come up with some numbers and reports to get your money. I asked some very simple questions and they couldn't not answer, and to me it shows that they are not professional and likely on the brink of their biz going bust. As my yelp title suggests, I hope they go out of biz so others can save their time and money. I am not haters. If you do a business, you must be good to deserve the money you make. If you are not good at what you do which people pay to you, you need to go disappear and stop messing around in the society. read more

This is an excellent company. I have now used them twice. Their service is quick, their paperwork is complete, their analysis are thorough, and the prices are right!! If you have questions about anything on their report, they put you in touch with a knowledgeable person that can help you understand the detail and the results. I plan to use them for future analysis and make them a permanent part of my maintenance routine. read more

Blackstone Labratories have always been prompt and professional with my test results. A personal touch is the summary they add to your test so you are not just looking at a bunch of numbers (even though the numbers are explained with norms and averages). My occupation is an aircraft mechanic since the 80's. SOAP (Spectographic Oil Analysis Program) is a way of life in airlines where you keep tabs on the health of large turbine engines and hydraulic systems. Finding a shift in norms allow repairs before they become costly or cancelling your flight. After purchasing a used vehicle, Blackstone noted a high silica content and suggested I inspect my intake system. There I found a broken clamp allowing air to bypass the air filter. Thanks BL . read more

I had a great experience. Knowledgeable staff (thanks Alex and Kristin) who are willing to take the time to answer any and all questions, and fast results! read more

Expertise is this company's strength. I used Blackstone for my routine aircraft engine oil change sampling and one day shortly after submitting a sample I received a phone call directly from them telling me they found a problem with my oil sample and urged me to not fly the aircraft until a mechanic checked for a piston wrist pin galling the side of a cylinder wall. Guess what the mechanic found? Exactly what the technician at Blackstone suspected. Needless to say, I now have a high degree of trust in this company. read more
