Engine heat block for warm weather

Sri Lanka, right? No, it would do no harm, but why bother? In your climate the improvement in fuel economy would be negligible.

 

If doing short trips it would help retain heat and do no harm to partially or fully block.

But for sustained driving, city or highway, I would remove grill blocking above ~50F (10C).

On balance I would not block, or block partial but watch temp. with a scangauge II or an ultragauge.

 

Are you referring to a grille block or an engine block heater?

 

Not that anyone has reported. Those of us who monitor engine temps do so with an add-on device like ScanGauge.

I agree that in milder climates it likely won't help.

 

Do Not grille block in that climate unless you constantly monitor engine temperature with a ScanGauge or the like. It would be far too easy to overheat and cause damage.

Is your fuel economy poor and you're looking for a remedy? or are you just having fun with the car?

 

From the FAQ over at GreenHybrid.com:

GreenHybrid - Hybrid Cars (last sentence under 4) Maintenance for MPG)

If this is accurate, sounds like year-round heating might very well be worth it to me! Combine that with the most commonly recommended fuel economy modifications such as low rolling resistance tires (ie. Michelin Energy Savers) pumped up a little higher than normal, an advanced fuel economy 0 or 10 weight oil (ie. Mobil 1 0w20) and you'll have three of the most significant and easily addressed mileage vampires covered from the moment you start your car... after that it's all up to personal driving style.

 

See posts 4 & 5 above where I sought and received clarification about whether the OP was looking for advice on an engine block heater or grille blocking. If he was looking for the former, I would agree with you. But that's not what he asked about.

 

Whoops... I guess I got all excited and jumped the gun with an answer to the wrong question! I'm gonna have to pay more attention when I read through these things! Sorry about that guys...

 

In a warm climate you will get much more improvement by using energy-efficient "low rolling resistance" tires. You can safely inflate any tire up to the maximum pressure stated on the side of the tire, which noticeably helps fuel economy. And of course always use the correct weight (5W-30, or as recommended in the Owner's Manual for your car) and quantity of oil. It can be risky to use a lighter weight oil especially in a hot climate because it may not lubricate well enough.
