There we have it folks …Additives used in the formulation since viscosity is basically equal at operating temperature.
"Taco tick". Normal. If it's not ticking....something probably wrong with it!My 4.0 Tacoma sounds different depending on time of day, temperature, astrological cycle, and whether or not another idler pulley is going out.
It’s ironic that one of the most reliable engines actually sounds like it’s going to shake itself apart at any moment.
I’ve never noticed a difference in sound after an oil change to a different brand. It just goes tickTicktickticktixktixktixktixcttickticktick no matter what - and will likely continue ticking well past 300k miles regardless of what I put in it.
And what's your reasoning?There we have it folks …
Never heard of a such thing. Oil is oil. Unless I don’t care enough to listenAn oil that seems to have a reputation for making an engine louder. I have one of those oils in a vehicle now and it is noticeably louder. Do you believe it's protecting less? More friction?
I don't see how a 'louder' oil could be louder without allowing more friction.
But I'm no engineer.
Thoughts?
My 2005 Tacoma 4.0L V6 is pretty quiet IMO, even compared to other vehicles I've owned over the years."Taco tick". Normal. If it's not ticking....something probably wrong with it!
Mine has 80k on it. My coworker's has 340k on it. They sound exactly the same at idle.
You must have ears that can put a hound dog to shameMy years as a Sonar operator mean I don't need an SPL meter to tell me there is a difference in output sound with different fluids inside an engine. Various elastomers and fluids can dampen the vibrational "Ringing" of metal parts simply by being in contact. Same result could probably be acheived cutting some sound mat and applying to valve cover/s and block.
Oh I wouldn't consider the ticking loud at all. But it's the nature of all the GR engines.My 2005 Tacoma 4.0L V6 is pretty quiet IMO, even compared to other vehicles I've owned over the years.
Yep, that's what you get with the DOHC and shim in bucket valve design - no hydraulics to keep valve shim clearance to zero.Oh I wouldn't consider the ticking loud at all. But it's the nature of all the GR engines.

^^^ Not everyone here is 65+ and hard of hearing, lol.
They still share the same 60° block, stroke, bore and, as far as I know, most of the lower internalsFWIW, the 1GR-FE in 2010 and newer FJ Cruisers, 4Runners, and Tundras, has almost nothing in common with the 1GR-FE in the Tacoma, or earlier FJ Cruisers, 4Runners, and Tundras, besides both being 4 Liter V6's.
It's so different, I can't understand why Toyota didn't change the engine model designation beyond stating Single VVT-i vs Dual VVT-i.
The Dual VVT-i version has roller rocker arms and hydraulic valve lash adjusters, amongst it's many changes.
