On my CRV; I find it very hard to check oil levels on its dipstick due to its design flaw or its thin oil...

Also I checked 2017 Acura TLX base, under the engine bay it looks the same as my CRV engine; I mean they did not even try to disguise a bit their resemblance...




If you have the most orange plastic tipped dip stick just razor knife the orange off, under it you'll find a normal blade, i did this recently couldn't be happier.







I think that orange plastic tip is there to prevent oil from migrating up the dipstick tube. Some engines have dipsticks with twists or bends that accomplish the same thing.

Is anyone using Amsoil SS in your 1.5TGDI? How does the engine like it so far? Is it doing any different in terms of fuel dilution?

I've been reading about correlation between high calcium concentration and LSPI frequency and it kind of concerns me. I have 0w20 SS in my hatch at the moment and feel really smooth and nice but I had it in fir 500miles only so it is really hard to make any judgement.

Anyway, looking forward to hear your thoughts on this.

First, I don't think oil brand has any influence on how much dilution occurs: that is a function of engine tuning and piston ring sealing. Second, if you believe high calcium oils contribute to LSPI in a way Honda hasn't anticipated, Amsoil would be about the worst choice imaginable as it is a very high calcium formula. If calcium worries you, go to Mobil1, which substitutes magnesium (not manganese) for calcium to a great extent.

I think Danh ment Castrol 0/40 A3/B4, Mobil 1 0/40 looks like an Amsoil on paper.

Assuming most 1.5T Civic owners would want to stick near the 20-weight spec'd viscosity I meant Mobil1. In 20 and 30 weight grades Mobil1 formulas available here are all low calcium/high magnesium.

Danh is correct on the Ca/Mg in lower M1 grades...I'm running the 0/40 M1 this summer but will eventually switch out to Castrol 0/40 for the lower Ca...don't want anything near a W20 even after dilution doing 3k hwy. a month like that..

Dblshock, how are you handling the warranty issue running 0w-40? Do you have an understanding with your dealer? Are you assuming the engine won't fail in the warranty period? Or that the dealer won't ask for documentation of oil changes? Or maybe that Honda would be cooperative despite the viscosity?

 

[dblshock]

I really don't think the engine has a conflict with the 40 grade oil, it runs fine, efficient...I would know if it was struggling, in order for Honda to object they'd have to prove the W40 was the problem on any given claim.

With high fuel dilution, its smart to use the excellent Mobil1 0w40 in a car that calls for 0w20.

WARNING! Crackpot theories ahead.
Maybe there is too much displacement for this type of application? The 1.5T drives like a larger displacement engine which makes some drivers reluctant to add any revs, like it's a 3.0 V6. Remember I said some, not all. These drivers are riding the low end torque to cruising speed. Why press on the gas more if the engine is providing enough acceleration at present throttle position? Lots of torque needs lots of advance on the timing, but there's 87 octane in the tank, so dial that back, add boost(power)and more fuel (for charge cooling) that doesn't burn and then factor in running on a flat road so there is plenty of cycling between on/off throttle and maybe these things could be a part of a myriad of contributing factors for fuel in the crankcase?
Manufacturers beat the c@ap out of their cars in testing before releasing their new models to the public. After starting an engine at -20 degrees F they jam it to full throttle and keep it at redline for however long it takes to rapidly disassemble or take it apart after days at red line.
Maybe this light throttle situation is something Honda figured wouldn't be severe enough?
Perhaps a smaller displacement engine would work a little harder with a few more revs and avoid this situation.

Well said Mr. 555. I drove my 1.5T exactly the way you described. 4700mi grandma style and oil got fuel diluted. This time around, I keep engine at 3-4rpm at all times (manual trans) and it seems to like it. It doesn't look like level rose at all, perhaps 2mm but it might be just measuring error. So far 1500mi on the oil and I plan on taking a sample and testing it at around 3K.

I hope it works out for you. That is a nice car with a very advanced engine. Enjoy it.

It should be interesting to watch and compare this Honda 1.5 engine to the new Mitsubishi 1.5 TGDI engine coming out next year in their new Eclipse Cross. Will they have similar issues? It could be a good comparison.

There is a new GM 1.5l DIT engine that already got recalled for LSPI problems. Not a good start for them!
