Question About 0W Oils

I use it in my Ford F150 truck as well as heavy equipment with diesel engines. I am so sold on 0-X oils that I will never go another winter with out using them. I presently use PetroCan 0-40 oil and have not had to use my engine block heater for the past close to 20 years. I don't know which oil company fist developed it but I am a firm believer in getting my oil pressure up as soon as possible. Esso is owned by exxonmobile in case you are wondering. Regards

Mark, first welcome to BITOG!

Why not use a 0W-20 in your F150 since a 20wt has been spec'd for your truck for quite a few years now.

Thanks for the welcome. You are correct about the 0W-20 spec for my truck. I have enough equipment and vehicles around me that I prefer to just use the same oil in everything. A matter of convenience I suppose.

Like other posters, I wouldn't agree with the too thin statement, either. Remember that there are plenty of vehicles on the road that specified 10w30 and many that specify 5w30. For the former, many people still use what was originally specified, and for that latter, many of those are still under warranty and call for 5w30 only.

Sure, a 0w30 would do the job in both cases, but I am not putting $10 per litre GC in my old F-150 when $2 per litre Quaker State conventional does the trick, and other people won't jeopardize their warranty on their newer vehicles. Simply put, there is a market for 10w30 and 5w30, and that's why they are on the shelves.

GC is an example of certainly not too thin for a 0w-30. It is a rather thick 30 weight, but with sufficient cold temperature pumpability to be called a 0w-30.

I suspect some have the perception that O=nothing, or no viscosity at all. If everyone knew what a great thing OW oils are, they wouldn't be as available for BITOG'ers.

Yes, granted, as long as the manufacturer did not have to add an abundance of shear unstable pour point depressants and viscosity index improvers in order to get that 0W-whatever!
