Running Mobil 1 ESP 0w-30 in my 2001 Chevy Blazer with the 4.3 Vortec. Have been running this oil for about 400-500 miles now. Drove from Columbia SC to Charlotte NC and back yesterday, and its was great. Oil pressure was slightly higher compared to api 5w-30 I’ve been running before. I read...

I just put in Mobil 1 ESP 0w30 in my 2001 Chevy Blazer with the 4.3 Vortec. 113K original miles when I put in ESP 0w30 in yesterday. I know, a little overkill for an old sbc vortec. But why not use this oil, it’s the best out there from what I’ve read on this forum, and it’s only $27 at my...

Was thinking about this for a while, but I am just now posting this. Is Valvoline Maxlife ATF really the best option for all makes and models? Are all ATF specs actually almost identical and similar enough for the Valvoline Maxlife ATF to work in literally all applications and transmissions...

Got a 4.3 vortec that is leaking some oil. It’s been leaking oil since I bought it 2 years ago, and the oil leak has not gotten any worse. I do 3k mile oil changes and I do not notice any oil level dropping on the dipstick, so it’s not a severe oil leak. The timing cover seal seems to be...

I got a 2001 Chevy Blazer 4x4 with the 4L60E. The truck has 112k original miles. I did a transmission flush and filter change about a year ago, and the transmission shifts and works awesome. I also sucked out 5 quarts of fluid and fill it back up with new fluid. No issues, it shifts and works...

I recently bought a vacuum fluid extraction pump for very cheap. I’ve attached a picture of the pump I bought. I’ve always been a diy backyard mechanic, and I fix everything on my own if it doesn’t require a lift, but I never owned or used a vacuum pump like this for some reason. Prior to buying...

I just did a coolant flush on my 2001 Chevy Blazer with the cast iron 4.3 Vortec. I put in Prestone Max Coolant, which is supposedly their longest lasting best coolant, and it’s a HOAT type based on the research I’ve done. The previous owner used Dexcool Orange coolant and I’m assuming quite a...

I recently came across a product called “ShinEtsu Silicone grease” on amazon. It seems like a product made for Hondas, might even be a Honda part number product. I read the reviews on Amazon and other forums and it seemed like the best product for rubber rejuvenating to keep them from cracking...

I haven’t been keeping up with ILSAC GF-7 SQ at all. I just read a post saying it’s coming next month on the 31st. I just heard about it few minutes ago. What differentiates the GF7 from GF6? I just feel like GF6 SP came out very recently, and it was supposed to be really good, and GF7 is...

Just want to know if I should just use the 10w30 version of the T6, or use the 5w30 multi vehicle API SN version? Is the 5w30 the same of quality as their non API SN rated T6 like the 10w30, 5w40, and 15w40? Asking because they are all the same price.

I’m getting ready to change my differential fluids (front and rear) on my 2001 Chevy Blazer 4door 4x4. Right now I have Supertech 80w90 Dino gear oil in the front and rear diffs, which I put in about a year ago. There’s no noise from the differentials, so they are in good shape. I just want...

I’ve been seeing ads of the “airless airbag” products this company makes all over the internet for a couple days now’s I haven’t found any videos on “pros and cons”, all I see is videos showing the airless airbags working on a vehicle, but with zero explanations. What’s the deal with this...

I have a 2001 Chevy Blazer with the 4.3 Vortec. It only has 107k miles. I bought it with 103,300 ish miles. So about 2 months ago, random misfires started occurring. I've been having random misfire issues on cylinder 1,2,3, and 4 for about two months. These cylinders are the two front...

I just bought some Goodyear wrangler Radials 235/75r/15. I believe goodyear discontinued these tires about 2 years ago. These are actually called Goodyear Wrangler Radial. NOT wrangler A/T, or whatever else wrangler tires they have. I bought it at Walmart and I’ll have them put it on my...

I got a 2001 Chevy Blazer 4.3 Vortec. 104k miles on her. Bought it at 103k miles, I’m the second owner. When I was in the process of buying this and going on test drives, I swear I did not hear this rattle sound. Maybe I just didn’t hear it because I got excited about buying a 2001 GM with...

Has anyone ever used this? What’s it made of? How does it work? My 2001 chevy blazer 4.3 Vortec with 103k miles had a timing cover leak. It was never enough to actually leave drips on the ground, but the bottom left corner of the timing cover was leaking. I tried tightening the bottom left...

I’ve seen a thread recently that was titled “M1 0w40 vs Castrol 0w40” and in there OVERKILL mentioned M1 FS 0w40 is now SP rated. The PDS from M1’s website now meantions that the FS 0w40 now meets or exceeds API SN+ and SP. So does that mean the calcium content has been decreased, and/or the...

I was just browsing on Mobil 1's website today and decided to look at the Safety Data sheet for the Mobil 1 EP 5w30. It looks like the SDS was revised on June 8, 2022, which is two days ago. I remember looking at the EP 5w30 SDS couple months ago and I know I saw 1-DECENE, TETRAMER AND TRIMER...

**Before I begin, I want to say that I might have left some typos and misspelled a couple words. I will fix those as time goes on and I find those errors.** I just wanted to post this, because as many of you know, people have been debating, discussing, and sometimes are even arguing and...
