Toyota Tundra Forum

When I got my last new truck I was still pretty old school when it came to oil changes and maintenance in general so when I saw in the owners manual that you could go over 7000 miles between oil changes and not void your warranty I was shocked, but also intrigued
so I had an analysis done by these folks just to prove it myself.

Well I'm happy to say that that led to me testing the threshold of the Mobil 1 extended drain Synthetic after my warranty had ran out and now with my driving style and geographical location I only change my oil every 12 thousand miles and have the analysis to prove the wisdom in doing this so anyone interested in having their oil analyzed you can get free kits from Blackstone labs. They will send you a collection kit for free and then it's only $22.50 to get the analysis done. For those of you who are running an extended drain (5000 miles +) for $10.00 more they will
give you the TBN (total base number) which measures the amount of active additive left in a sample of oil.
Everything you need to read your analysis is here from Bob the oil guy and by the way Blackstone labs also will test your tranny fluid for you.

Good Gawd Squid that is one ugly Tundra.

Blackstone is excellent! I've used them in the past and plan on using them again shortly when my Tundra is up for an oil change. I will add that Blackstone is by far the cheapest and best turn around time for analysis. Others I've been quoted $35 for the UOA and they stated their turn around times are 10-14 days. Blackstone, even though I live 80 miles from them, usually has the report e-mailed to me within 4 days and I recieve a paper copy within 7.

No doubt about it, well worth the money. By the way I really like your fast black truck!

yeah, like your truck and thanks for the info

Just got oil analysis back from Blackstone labs. This was the fist time I used them and it's pretty sweet. They break down everything for you and put it in a report that's easy to understand. I feel that it was worth the $22.50 because at least now I can compare each oil change to the last and see what's going on, and if there ever is a problem and the dealer tries to pull some b.s. about me not changing the oil I now have proof. I am going to do this with all of my trucks now.
