Thanks. I thought so too. Even it works fine, Toyota can still use this to void my power train waranty. In fact on the driver side of the cylinder head, there is a sign warning against a shorter spark plug.
What troubles me is on the E3 web site as well as at the local parts store (Kragen...
Has anyone used E3 (E3.56) Spark Plugs? I bought a set for 2004 SR5 V6. The plugs are actually shorter than OEM. If it is shorter, does it recess into the cylinder wall, or just not protrude as much? Should I return them and get a refund?
THANKS!
The Owner Manual says: 5W30 is for "good fuel economy and good starting in cold weather" and suppose to switch back to 5W30 "at next oil change" after 10W30. I figured with 10W30 it would be bad for cold starting like you said and for fuel economy...
BTW, I did a bit more searching...
My 04 4Runner had a similar symptom recently, just like starting a flooded engine --- slow crank and rpm builds up slowly in a cold morning (< 40F). It was after I forgot to put back the gas cap in a rain after putting in gas..... A tankful or two later when CA had this cold snap this past...
I have an 04 4Runner, today when I changed oil, by mistake I put one qt of 10W-30 with 4.5 qt of 5W-30, same brand. Should I worry about it?
The Owner's manual says it is OK occasionally use 10W-30 though feul economy may suffer. It said nothing about mixed viscosity in the same crank case.
