Hi elkid, A 60/40 TGMO/M1 ratio shouldn't be too light for your '89 Integra with a HTHSV on par with AFE 0W-30 and M1 10W-30 if not slightly higher. Or you could go with the simplicity of a 50/50 blend and your HTHSV will only be slightly heavier than a typical 5W-30 and still be lighter on...

Originally Posted By: lubricatosaurus Rotella T6 will work very well. Not that much difference hot. Thicker oil films are not a problem. There is a large difference in hot viscosity between a HTHSV 2.6cP oil 0W/5W-20 and the 4.0cP HTHSV of Rotella, the problem being reduced oil flow. But the...

Originally Posted By: donnyj08 Redline 5w20 Has an HTHS of 3.0 It is basically a 30wt as it is thicker than the 2.9cp min allowed for a 30wt oil. There wont be any problem running it. It also will not flow any better than a typical 5w30 at missouri temps. VI is 147 so it is not exactly the...

Leaving a bottle upturned in the oil fill hole for just a few minutes while he does other car maintenance will leave only a trace of oil in the bottle. To be worthwhile he would have to leave a fair amount of oil in each bottle and or he's keeping half filled bottles for himself instead of...

Originally Posted By: JOD The TBN listed is higher than on the VOA's I've seen with this oil! I realize that there's some variance between labs, but it's still surprising. I pulled a sample to send in from my last oil change with this oil, because I'm a bit lost on how long to run it--and I...

I believe it's still possible to formulate a SN 5W-20 or 5W-30 without using any GP III but you would have to use a high percentage of GP II+. So it might be easier/cheaper for a formulator to just use a GP III as a correcting fluid applied to the GP II stocks a formulator may have. Or if...

You mentioned your very short commute of only 3 miles but not your annual mileage? How many miles are on your current oil fill and when was it last changed? If as I suspect the time interval and mileage is very low I would recommend not changing the oil until after your "Nevada winter". As for...

Yes it's all about brand presentation. I'm sure it's the identical oil as TGMO 0W-20. Here in Canada Acura does the same thing with their Acura brand 0W-20 which is the same oil as the Honda brand 0W-20 and the last time I checked the pricing was the same as well.

You're askng the wrong question. There are many many brands that make some excellent motor oils. But I don't know of a single brand that also doesn't have some mediocre and/or unsuitable oils in their line up. So forget about the brand and the marketing and choose an oil based on it's actual...

Toyota Canada has back-spec'd the 5W-20 grade for earlier model yearSequoias. The latest version of TGMO 0W-20 is recommended for 5W-20 applications so that is the oil I would use in a Pennsylvania climate.

Of course just because a couple of formulators have the grade in their product line up doesn't mean it's available or that they will be the first to market. Honda et al still haven't specified the grade for any North American sold vehicle yet so until they do no retailer is going to order it...

Yes it's okay although it's certainly not the best way to thicken up a 5W-30 due to it's very low VI. Probably the best and most cost effective way to increase the viscosity of a 5W-30 is to blend in some M1 0W-40. This way you're maximizing the increase in viscosity at operating temp's while...
